Understanding Desktop Video Solutions, How They Scale, Bandwidth Considerations and Their Total Cost of Ownership. An analyst report by Dr. Brent Kelly of Constellation Research.
A successful data migration process can be used for a one-time migration, or as a standard procedure for future migrations employing a consistent, reliable and repeatable methodology incorporating planning, tool implementation and validation. Dell data migration services can help. This whitepaper explores the Dell storage portfolio, Dell methodologies for migration and the use cases for migrating customers over to Dell Storage.
Creating a VMware Software-Defined Data Center Reference Architecture EMC
This reference architecture describes an implementation of a software-defined data center (SDDC) using VMware vCloud® Suite Enterprise 5.8, VMware NSXTM for vSphere® 6.1, VMware IT Business Management SuiteTM Standard Edition 1.1, and VMware vCenterTM Log InsightTM 2.0 to create an SDDC. This SDDC implementation is based on real-world scenarios, user workloads, and infrastructure system configurations. The configuration uses industry-standard servers, IP-based storage, and 10-Gigabit Ethernet (10GbE) networking to support a scalable and redundant architecture.
An overview of the solution and the logical architecture as well as results of the tested physical implementation are provided. Consult with your VMware representative as to how to modify the architecture to suit your business needs.

White Paper: Look Before You Leap Into Google AppsOffice
Many IT organizations that have evaluated Google Apps have found that the projected versus actual costs of switching to Google Apps greatly increase their total cost of ownership (TCO). This white paper discusses three major hidden-cost areas associated with Google Apps: Deployment costs, IT Support costs, and User Training and File Fidelity costs.
This whitepaper examines the challenges in integrating malware protection into broader product offerings, provides an in-depth review of the VIPRE® SDK, and covers the benefits of partnering with the GFI Advanced Technology Group to deliver the most efficient and effective protection solutions available.

Disc Drive: CD or DVD-ROM drive if installing from CD
Note: GridView for ASP.NET AJAX requires Microsoft ASP.NET AJAX Extensions installed and a ScriptManager on
the page before the C1GridView control is placed on the page. You must create an ASP.NET AJAX-Enabled Project
so that the ScriptManager and Microsoft AJAX Extensions are included on the page. For more information, see
Creating an AJAX-Enabled ASP.NET Project (page 18). For more information about Microsoft ASP.NET AJAX Extensions,
see http://ajax.asp.net/. For information about the ScriptManager, see MSDN.
Installing Demonstration Versions
If you wish to try GridView for ASP.NET AJAX and do not have a serial number, follow the steps through the
installation wizard and use the default serial number.
The only difference between unregistered (demonstration) and registered (purchased) versions of our products is
that registered versions will stamp every application you compile so a ComponentOne banner will not appear
when your users run the applications.

14. Deploying your Application in a Medium Trust Environment
Depending on your hosting choice, you may need to deploy your Web site or application in a medium trust
environment. Often in a shared hosting environment, medium trust is required. In a medium trust environment
several permissions are unavailable or limited, including OleDbPermission, ReflectionPermission, and
FileIOPermission. You can configure your Web.config file to enable these permissions.
Note: ComponentOne controls will not work in an environment where reflection is not allowed.
ComponentOne ASP.NET controls include the AllowPartiallyTrustedCallers() assembly attribute and will work
under the medium trust level with some changes to the Web.config file. Since this requires some control over the
Web.config file, please check with your particular host to determine if they can provide the rights to override these
security settings.
Modifying or Editing the Config File
In order to add permissions, you can edit the exiting web_mediumtrust.config file or create a custom policy file
based on the medium trust policy. If you modify the existing web_mediumtrust.config file, all Web applications
will have the same permissions with the permissions you have added. If you want applications to have different
permissions, you can instead create a custom policy based on medium trust.
Edit the Config File
In order to add permissions, you can edit the exiting web_mediumtrust.config file. To edit the exiting
web_mediumtrust.config file, complete the following steps:
1. Locate the medium trust policy file web_mediumtrust.config located by default in the
%windir%Microsoft.NETFramework{Version}CONFIG directory.
2. Open the web_mediumtrust.config file.
3. Add the permissions that you want to grant. For examples, see Adding Permissions (page 9).
Create a Custom Policy Based on Medium Trust
In order to add permissions, you can create a custom policy file based on the medium trust policy. To create a
custom policy file, complete the following steps:
1. Locate the medium trust policy file web_mediumtrust.config located by default in the
%windir%Microsoft.NETFramework{Version}CONFIG directory.
2. Copy the web_mediumtrust.config file and create a new policy file in the same directory.
Give the new a name that indicates that it is your variation of medium trust; for example,
AllowReflection_Web_MediumTrust.config.
3. Add the permissions that you want to grant. For examples, see Adding Permissions (page 9).
4. Enable the custom policy file on your application by modifying the following lines in your web.config file
under the <system.web> node:
<system.web>
<trust level="CustomMedium" originUrl=""/>
<securityPolicy>
<trustLevel name="CustomMedium"
policyFile="AllowReflection_Web_MediumTrust.config"/>
</securityPolicy>
...
</system.web>
Note: Your host may not allow trust level overrides. Please check with your host to see if you have these rights.

15. Allowing Deserialization
To allow the deserialization of the license added to App_Licenses.dll by the Microsoft IDE, you should add the
SerializationFormatter flag to security permission to the Web.config file. Complete the steps in the Modifying or
Editing the Config File (page 8) topic to create or modify a policy file before completing the following.
Add the SerializationFormatter flag to the <IPermission class="SecurityPermission"> tag so
that it appears similar to the following:
<NamedPermissionSets>
<PermissionSet
class="NamedPermissionSet"
version="1"
Name="ASP.Net">
<IPermission
class="SecurityPermission"
version="1"
Flags="Assertion, Execution, ControlThread,
ControlPrincipal, RemotingConfiguration, SerializationFormatter"/>
...
</PermissionSet>
</NamedPermissionSets>
Adding Permissions
You can add permission, including ReflectionPermission, OleDbPermission, and FileIOPermission, to the
web.config file. Note that ComponentOne controls will not work in an environment where reflection is not
allowed. Complete the steps in the Modifying or Editing the Config File (page 8) topic to create or modify a policy
file before completing the following.
ReflectionPermission
By default ReflectionPermission is not available in a medium trust environment. ComponentOne ASP.NET
controls require reflection permission because LicenseManager.Validate() causes a link demand for full trust.
To add reflection permission, complete the following:
1. Open the web_mediumtrust.config file or a file created based on the web_mediumtrust.config file.
2. Add the following <SecurityClass> tag after the <SecurityClasses> tag so that it appears similar
to the following:
<SecurityClasses>
<SecurityClass Name="ReflectionPermission"
Description="System.Security.Permissions.ReflectionPermission, mscorlib,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
...
</SecurityClasses>
3. Add the following <IPermission> tag after the <NamedPermissionSets> tag so it appears similar
to the following:
<NamedPermissionSets>
<PermissionSet class="NamedPermissionSet" version="1"
Name="ASP.Net">
<IPermission
class="ReflectionPermission"
version="1"
Flags="ReflectionEmit,MemberAccess" />
...
</PermissionSet>
</NamedPermissionSets>
4. Save and close the web_mediumtrust.config file.
9
16. OleDbPermission
By default OleDbPermission is not available in a medium trust environment. This means you cannot use the
ADO.NET managed OLE DB data provider to access databases. If you wish to use the ADO.NET managed OLE
DB data provider to access databases, you must modify the web_mediumtrust.config file.
To add OleDbPermission, complete the following steps:
1. Open the web_mediumtrust.config file or a file created based on the web_mediumtrust.config file.
2. Add the following <SecurityClass> tag after the <SecurityClasses> tag so that it appears similar
to the following:
<SecurityClasses>
<SecurityClass Name="OleDbPermission"
Description="System.Data.OleDb.OleDbPermission, System.Data,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
...
</SecurityClasses>
3. Add the following <IPermission> tag after the <NamedPermissionSets> tag so it appears similar
to the following:
<NamedPermissionSets>
<PermissionSet class="NamedPermissionSet" version="1"
Name="ASP.Net">
<IPermission class="OleDbPermission" version="1"
Unrestricted="true"/>
...
</PermissionSet>
</NamedPermissionSets>
4. Save and close the web_mediumtrust.config file.
FileIOPermission
By default, FileIOPermission is not available in a medium trust environment. This means no file access is
permitted outside of the application's virtual directory hierarchy. If you wish to allow additional file permissions,
you must modify the web_mediumtrust.config file.
To modify FileIOPermission to allow read access to a specific directory outside of the application's virtual
directory hierarchy, complete the following steps:
1. Open the web_mediumtrust.config file or a file created based on the web_mediumtrust.config file.
2. Add the following <SecurityClass> tag after the <SecurityClasses> tag so that it appears
similar to the following:
<SecurityClasses>
<SecurityClass Name="FileIOPermission"
Description="System.Security.Permissions.FileIOPermission, mscorlib,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
...
</SecurityClasses>
3. Add the following <IPermission> tag after the <NamedPermissionSets> tag so it appears similar
to the following:
<NamedPermissionSets>
<PermissionSet class="NamedPermissionSet" version="1"
Name="ASP.Net">
...
<IPermission class="FileIOPermission" version="1"
Read="C:SomeDir;$AppDir$" Write="$AppDir$" Append="$AppDir$"
PathDiscovery="$AppDir$" />
...
10
17. </PermissionSet>
</NamedPermissionSets>
4. Save and close the web_mediumtrust.config file.
End-User License Agreement
All of the ComponentOne licensing information, including the ComponentOne end-user license agreements,
frequently asked licensing questions, and the ComponentOne licensing model, is available online at
http://www.componentone.com/SuperPages/Licensing/.
Licensing FAQs
This section describes the main technical aspects of licensing. It may help the user to understand and resolve
licensing problems he may experience when using ComponentOne WinForms and ASP.NET products.
What is Licensing?
Licensing is a mechanism used to protect intellectual property by ensuring that users are authorized to use software
products.
Licensing is not only used to prevent illegal distribution of software products. Many software vendors, including
ComponentOne, use licensing to allow potential users to test products before they decide to purchase them.
Without licensing, this type of distribution would not be practical for the vendor or convenient for the user.
Vendors would either have to distribute evaluation software with limited functionality, or shift the burden of
managing software licenses to customers, who could easily forget that the software being used is an evaluation
version and has not been purchased.
How does Licensing Work?
ComponentOne uses a licensing model based on the standard set by Microsoft, which works with all types of
components.
Note: The Compact Framework components use a slightly different mechanism for run-time licensing than the
other ComponentOne components due to platform differences.
When a user decides to purchase a product, he receives an installation program and a Serial Number. During the
installation process, the user is prompted for the serial number that is saved on the system. (Users can also enter
the serial number by clicking the License button on the About Box of any ComponentOne product, if available, or
by rerunning the installation and entering the serial number in the licensing dialog box.)
When a licensed component is added to a form or Web page, Visual Studio obtains version and licensing
information from the newly created component. When queried by Visual Studio, the component looks for
licensing information stored in the system and generates a run-time license and version information, which Visual
Studio saves in the following two files:
An assembly resource file which contains the actual run-time license
A "licenses.licx" file that contains the licensed component strong name and version information
These files are automatically added to the project.
In WinForms and ASP.NET 1.x applications, the run-time license is stored as an embedded resource in the
assembly hosting the component or control by Visual Studio. In ASP.NET 2.x applications, the run-time license
may also be stored as an embedded resource in the App_Licenses.dll assembly, which is used to store all run-time
licenses for all components directly hosted by WebForms in the application. Thus, the App_licenses.dll must
always be deployed with the application.
11
18. The licenses.licx file is a simple text file that contains strong names and version information for each of the
licensed components used in the application. Whenever Visual Studio is called upon to rebuild the application
resources, this file is read and used as a list of components to query for run-time licenses to be embedded in the
appropriate assembly resource. Note that editing or adding an appropriate line to this file can force Visual Studio
to add run-time licenses of other controls as well.
Note that the licenses.licx file is usually not shown in the Solution Explorer; it appears if you press the Show All
Files button in the Solution Explorer's Toolbox, or from Visual Studio's main menu, select Show All Files on the
Project menu.
Later, when the component is created at run time, it obtains the run-time license from the appropriate assembly
resource that was created at design time and can decide whether to simply accept the run-time license, to throw an
exception and fail altogether, or to display some information reminding the user that the software has not been
licensed.
All ComponentOne products are designed to display licensing information if the product is not licensed. None will
throw licensing exceptions and prevent applications from running.
Common Scenarios
The following topics describe some of the licensing scenarios you may encounter.
Creating components at design time
This is the most common scenario and also the simplest: the user adds one or more controls to the form, the
licensing information is stored in the licenses.licx file, and the component works.
Note that the mechanism is exactly the same for Windows Forms and Web Forms (ASP.NET) projects.
Creating components at run time
This is also a fairly common scenario. You do not need an instance of the component on the form, but would like
to create one or more instances at run time.
In this case, the project will not contain a licenses.licx file (or the file will not contain an appropriate run-time
license for the component) and therefore licensing will fail.
To fix this problem, add an instance of the component to a form in the project. This will create the licenses.licx file
and things will then work as expected. (The component can be removed from the form after the licenses.licx file
has been created).
Adding an instance of the component to a form, then removing that component, is just a simple way of adding a
line with the component strong name to the licenses.licx file. If desired, you can do this manually using notepad or
Visual Studio itself by opening the file and adding the text. When Visual Studio recreates the application resources,
the component will be queried and its run-time license added to the appropriate assembly resource.
Inheriting from licensed components
If a component that inherits from a licensed component is created, the licensing information to be stored in the
form is still needed. This can be done in two ways:
Add a LicenseProvider attribute to the component.
This will mark the derived component class as licensed. When the component is added to a form, Visual
Studio will create and manage the licenses.licx file, and the base class will handle the licensing process as
usual. No additional work is needed. For example:
[LicenseProvider(typeof(LicenseProvider))]
class MyGrid: C1.Win.C1FlexGrid.C1FlexGrid
{
// ...
}
12
19. Add an instance of the base component to the form.
This will embed the licensing information into the licenses.licx file as in the previous scenario, and the
base component will find it and use it. As before, the extra instance can be deleted after the licenses.licx
file has been created.
Please note, that C1 licensing will not accept a run-time license for a derived control if the run-time license is
embedded in the same assembly as the derived class definition, and the assembly is a DLL. This restriction is
necessary to prevent a derived control class assembly from being used in other applications without a design time
license. If you create such an assembly, you will need to take one of the actions previously described create a
component at run time.
Using licensed components in console applications
When building console applications, there are no forms to add components to, and therefore Visual Studio won't
create a licenses.licx file.
In these cases, create a temporary Windows Forms application and add all the desired licensed components to a
form. Then close the Windows Forms application and copy the licenses.licx file into the console application
project.
Make sure the licenses.licx file is configured as an embedded resource. To do this, right-click the licenses.licx file in
the Solution Explorer window and select Properties. In the Properties window, set the Build Action property to
Embedded Resource.
Using licensed components in Visual C++ applications
There is an issue in VC++ 2003 where the licenses.licx is ignored during the build process; therefore, the licensing
information is not included in VC++ applications.
To fix this problem, extra steps must be taken to compile the licensing resources and link them to the project. Note
the following:
1. Build the C++ project as usual. This should create an .exe file and also a licenses.licx file with licensing
information in it.
2. Copy the licenses.licx file from the application directory to the target folder (Debug or Release).
3. Copy the C1Lc.exe utility and the licensed DLLs to the target folder. (Don't use the standard lc.exe, it has
bugs.)
4. Use C1Lc.exe to compile the licenses.licx file. The command line should look like this:
c1lc /target:MyApp.exe /complist:licenses.licx /i:C1.Win.C1FlexGrid.dll
5. Link the licenses into the project. To do this, go back to Visual Studio, right-click the project, select
Properties, and go to the Linker/Command Line option. Enter the following:
/ASSEMBLYRESOURCE:DebugMyApp.exe.licenses
6. Rebuild the executable to include the licensing information in the application.
Using licensed components with automated testing products
Automated testing products that load assemblies dynamically may cause them to display a license dialog box. This
is the expected behavior since the test application typically does not contain the necessary licensing information,
and there is no easy way to add it.
This can be avoided by adding the string "C1CheckForDesignLicenseAtRuntime" to the AssemblyConfiguration
attribute of the assembly that contains or derives from ComponentOne controls. This attribute value directs the
ComponentOne controls to use design-time licenses at run time.
For example:
#if AUTOMATED_TESTING
[AssemblyConfiguration("C1CheckForDesignLicenseAtRuntime")]
13
20. #endif
public class MyDerivedControl : C1LicensedControl
{
// ...
}
Note that the AssemblyConfiguration string may contain additional text before or after the given string, so the
AssemblyConfiguration attribute can be used for other purposes as well. For example:
[AssemblyConfiguration("C1CheckForDesignLicenseAtRuntime,BetaVersion")]
THIS METHOD SHOULD ONLY BE USED UNDER THE SCENARIO DESCRIBED. It requires a design
time license to be installed on the testing machine. Distributing or installing the license on other computers is a
violation of the EULA.
Troubleshooting
We try very hard to make the licensing mechanism as unobtrusive as possible, but problems may occur for a
number of reasons.
Below is a description of the most common problems and their solutions.
I have a licensed version of a ComponentOne product but I still get the splash screen when I run my
project.
If this happens, there may be a problem with the licenses.licx file in the project. It either doesn't exist, contains
wrong information, or is not configured correctly.
First, try a full rebuild (Rebuild All from the Visual Studio Build menu). This will usually rebuild the correct
licensing resources.
If that fails follow these steps:
1. Open the project and go to the Solution Explorer window.
2. Click the Show All Files button on the top of the window.
3. Find the licenses.licx file and open it. If prompted, continue to open the file.
4. Change the version number of each component to the appropriate value. If the component does not
appear in the file, obtain the appropriate data from another licenses.licx file or follow the alternate
procedure following.
5. Save the file, then close the licenses.licx tab.
6. Rebuild the project using the Rebuild All option (not just Rebuild).
Alternatively, follow these steps:
1. Open the project and go to the Solution Explorer window.
2. Click the Show All Files button on the top of the window.
3. Find the licenses.licx file and delete it.
4. Close the project and reopen it.
5. Open the main form and add an instance of each licensed control.
6. Check the Solution Explorer window, there should be a licenses.licx file there.
7. Rebuild the project using the Rebuild All option (not just Rebuild).
For ASP.NET 2.x applications, follow these steps:
1. Open the project and go to the Solution Explorer window.
2. Find the licenses.licx file and right-click it.
14
21. 3. Select the Rebuild Licenses option (this will rebuild the App_Licenses.licx file).
4. Rebuild the project using the Rebuild All option (not just Rebuild).
I have a licensed version of a ComponentOne product on my Web server but the components still
behave as unlicensed.
There is no need to install any licenses on machines used as servers and not used for development.
The components must be licensed on the development machine, therefore the licensing information will be saved
into the executable (.exe or .dll) when the project is built. After that, the application can be deployed on any
machine, including Web servers.
For ASP.NET 2.x applications, be sure that the App_Licenses.dll assembly created during development of the
application is deployed to the application bin directory on the Web server.
If your ASP.NET application uses WinForms user controls with constituent licensed controls, the run-time license
is embedded in the WinForms user control assembly. In this case, you must be sure to rebuild and update the user
control whenever the licensed embedded controls are updated.
I downloaded a new build of a component that I have purchased, and now I'm getting the splash screen
when I build my projects.
Make sure that the serial number is still valid. If you licensed the component over a year ago, your subscription
may have expired. In this case, you have two options:
Option 1 – Renew your subscription to get a new serial number.
If you choose this option, you will receive a new serial number that you can use to license the new components
(from the installation utility or directly from the About Box).
The new subscription will entitle you to a full year of upgrades and to download the latest maintenance builds
directly from http://prerelease.componentone.com/.
Option 2 – Continue to use the components you have.
Subscriptions expire, products do not. You can continue to use the components you received or downloaded while
your subscription was valid.

Namespaces
Namespaces organize the objects defined in an assembly. Assemblies can contain multiple namespaces, which can
in turn contain other namespaces. Namespaces prevent ambiguity and simplify references when using large groups
of objects such as class libraries.
The general namespace for ComponentOne Web products is C1.Web.UI.Controls. The following code fragment
shows how to declare a C1GridView using the fully qualified name for this class:
Visual Basic
Dim GridView As C1.Web.UI.Controls.C1GridView
C#
C1.Web.UI.Controls.C1GridView GridView;
Namespaces address a problem sometimes known as namespace pollution, in which the developer of a class library is
hampered by the use of similar names in another library. These conflicts with existing components are sometimes
called name collisions.
Fully qualified names are object references that are prefixed with the name of the namespace where the object is
defined. You can use objects defined in other projects if you create a reference to the class (by choosing Add
Reference from the Project menu) and then use the fully qualified name for the object in your code.
Fully qualified names prevent naming conflicts because the compiler can always determine which object is being
used. However, the names themselves can get long and cumbersome. To get around this, you can use the Imports
statement (using in C#) to define an alias — an abbreviated name you can use in place of a fully qualified name.
For example, the following code snippet creates aliases for two fully qualified names, and uses these aliases to
define two objects:
Visual Basic
Imports C1GridView = C1.Web.UI.Controls.C1GridView
Imports MyGridView = MyProject.Objects.C1GridView
Dim grid1 As C1GridView
Dim grid2 As MyGridView
C#
using C1GridView = C1.Web.UI.Controls.C1GridView;
using MyGridView = MyProject.Objects.C1GridView;
C1GridView grid1;
MyGridView grid2;
If you use the Imports statement without an alias, you can use all the names in that namespace without
qualification provided they are unique to the project.

24. Creating an AJAX-Enabled ASP.NET Project
ComponentOne GridView for ASP.NET AJAX requires you to create an ASP.NET AJAX-Enabled project so
that Microsoft ASP.NET AJAX Extensions and a ScriptManager control are included in your project before the
C1GridView control is placed on the page. This allows you to take advantage of ASP.NET AJAX and certain
features such as partial-page rendering and client-script functionality of the Microsoft AJAX Library.
When creating AJAX-Enabled ASP.NET projects, Visual Studios 2008 and 2005 both give you the option of
creating a Web site project or a Web application project. MSDN provides detailed information on why you would
choose one option over the other.
If you are using Visual Studio 2008 with .NET Framework 2.0 or .NET Framework 3.0 or if you are using Visual
Studio 2005, you must install the ASP.NET AJAX Extensions 1.0, which can be found at http://ajax.asp.net/.
Additionally for Visual Studio 2005 users, creating a Web application project requires installation of a Visual
Studio 2005 update and add-in, which can be found at http://msdn.microsoft.com/; however, if you have Visual
Studio 2005 SP1, Web application project support is included and a separate download is not required.
If you are using Visual Studio 2008 and .NET Framework 3.5, you can easily create an AJAX-enabled ASP.NET
project without installing separate add-ins because the framework has a built-in AJAX library and controls.
Note: If you are using Visual Studio 2010, see http://www.asp.net/ajax/ for more information on creating an AJAX-
Enabled ASP.NET Project.
The following table summarizes the installations needed:
Visual Studio Version Additional Installation Requirements
Visual Studio 2008, .NET Framework 3.5 None
Visual Studio 2008 and .NET Framework 2.0 ASP.NET AJAX Extensions 1.0
or 3.0
http://www.asp.net/ajax/downloads/archive/
Visual Studio 2005 Service Pack 1
Visual Studio 2005 ASP.NET AJAX Extensions 1.0
Visual Studio update and add-in (2 installs for Web
application project support)
The following topics explain how to create both types of projects in Visual Studio 2008 and 2005.
Creating an AJAX-Enabled Web Site Project in Visual Studio 2008
To create a Web site project in Visual Studio 2008, complete the following steps:
1. From the File menu, select New | Web Site. The New Web Site dialog box opens.
2. Select .NET Framework 3.5 or the desired framework in the upper right corner. Note that if you choose
.NET Framework 2.0 or 3.0, you must install the extensions first.
3. In the list of templates, select AJAX 1.0-Enabled ASP.NET 2.0 Web Site.
4. Click Browse to specify a location and then click OK.
Note: The Web server must have IIS version 6 or later and the .NET Framework installed on it. If you
have IIS on your computer, you can specify http://localhost for the server.
18
25. A new AJAX-Enabled Web Site is created at the root of the Web server you specified. In addition, a
new Web Forms page called Default.aspx is displayed and a ScriptManager control is placed on the
form. The ScriptManger is needed to enable certain features of ASP.NET AJAX such as partial-page
rendering, client-script functionality of the Microsoft AJAX Library, and Web-service calls.
Creating an AJAX-Enabled Web Application Project in Visual Studio 2008
To create a new Web application project in Visual Studio 2008, complete the following steps.
1. From the File menu, select New | Project. The New Project dialog box opens.
2. Select .NET Framework 3.5 or the desired framework in the upper right corner. Note that if you choose
.NET Framework 2.0 or 3.0, you must install the extensions first.
3. Under Project Types, choose either Visual Basic or Visual C# and then select Web. Note that one of
these options may be located under Other Languages.
4. Select AJAX 1.0-Enabled ASP.NET 2.0 Web Application from the list of Templates in the right pane.
5. Enter a URL for your application in the Location field and click OK.
Note: The Web server must have IIS version 6 or later and the .NET Framework installed on it. If you
have IIS on your computer, you can specify http://localhost for the server.
A new Web Forms project is created at the root of the Web server you specified. In addition, a new
Web Forms page called Default.aspx is displayed and a ScriptManager control is placed on the form.
The ScriptManger is needed to enable certain features of ASP.NET AJAX such as partial-page
rendering, client-script functionality of the Microsoft AJAX Library, and Web-service calls.
Creating an AJAX-Enabled Web Site Project in Visual Studio 2005
To create a Web site project in Visual Studio 2005, complete the following steps:
1. From the File menu in Microsoft Visual Studio .NET, select New Web Site. The New Web Site dialog box
opens.
2. Select ASP.NET AJAX-Enabled Web Site from the list of Templates.
3. Enter a URL for your site in the Location field and click OK.
Note: The Web server must have IIS version 6 or later and the .NET Framework installed on it. If you
have IIS on your computer, you can specify http://localhost for the server.
A new Web Forms project is created at the root of the Web server you specified. In addition, a new
Web Forms page called Default.aspx is displayed and a ScriptManager control is placed on the form.
The ScriptManger is needed to enable certain features of ASP.NET AJAX such as partial-page
rendering, client-script functionality of the Microsoft AJAX Library, and Web-service calls.
Creating an AJAX-Enabled Web Application Project in Visual Studio 2005
To create a new Web application project in Visual Studio 2005, complete the following steps.
1. From the File menu in Microsoft Visual Studio 2005, select New Project. The New Project dialog box
opens.
19
26. 2. Under Project Types, choose either Visual Basic Projects or Visual C# Projects. Note that one of these
options may be located under Other Languages.
3. Select ASP.NET AJAX-Enabled Web Application from the list of Templates in the right pane.
4. Enter a URL for your application in the Location field and click OK.
Note: The Web server must have IIS version 6 or later and the .NET Framework installed on it. If you
have IIS on your computer, you can specify http://localhost for the server.
A new Web Forms project is created at the root of the Web server you specified. In addition, a new
Web Forms page called Default.aspx is displayed and a ScriptManager control is placed on the form.
The ScriptManger is needed to enable certain features of ASP.NET AJAX such as partial-page
rendering, client-script functionality of the Microsoft AJAX Library, and Web-service calls.
Adding the C1GridView Component to a Project
When you install ComponentOne Studio for ASP.NET AJAX, the Create a ComponentOne Visual Studio
Toolbox Tab check box is checked, by default, in the installation wizard. When you open Visual Studio, you will
notice a ComponentOne Studio for ASP.NET AJAX tab containing the ComponentOne controls has
automatically been added to the Toolbox.
If you decide to uncheck the Create a ComponentOne Visual Studio Toolbox Tab check box during installation,
you can manually add ComponentOne controls to the Toolbox at a later time.
ComponentOne GridView for ASP.NET AJAX provides the C1GridView control. C1GridView is the
component used to generate a table of items that can be selected, edited, deleted and sorted.
To use C1GridView, add it to the form or add a reference to the C1.Web.UI.Controls.C1GridView assembly to
your project.
Manually Adding a C1GridView Component to the Toolbox
To add C1GridView to the Visual Studio Toolbox:
1. Open the Visual Studio IDE (Microsoft Development Environment). Make sure the Toolbox is visible
(select Toolbox in the View menu, if necessary) and right-click it to open the Toolbox context menu.
2. If you want the C1GridView component to appear on its own tab in the Toolbox, select Add Tab from the
context menu and type in the tab name, C1GridView, for example.
3. Right-click the tab where the component is to appear and select Choose Items from the context menu.
The Choose Toolbox Items dialog box opens.
4. In the Choose Toolbox Items dialog box, select the .NET Framework Components tab. Sort the list by
Namespace (click the Namespace column header) and check the check box for the component belonging to
namespace C1.Web.UI.Controls.C1GridView.
Adding a C1GridView Component to the Form
To add C1GridView to a form:
1. Add it to the Visual Studio Toolbox.
2. Double-click the control or drag it onto your form.
Adding a Reference to the Assembly
To add a reference to the C1.Web.UI.Controls.C1GridView.2 assembly:
1. Select the Add Reference option from the Project menu of your Web application project. This option is
on the Website menu for Web site projects.
20
27. 2. Select the ComponentOne C1GridView assembly from the list on the .NET tab or browse to find the
C1.Web.UI.Controls.2.dll (or C1.Web.UI.Controls.3.dll) file and click OK.
3. Double-click the Default.aspx page to open the code window. At the top of the file, add the following
Imports statement (using in C#):
Imports C1.Web.UI.Controls.C1GridView
Note: This makes the objects defined in the C1GridView assembly visible to the project. See Namespaces
(page 17) for more information.
Upgrading From WebGrid for ASP.NET
If you're currently a user of the C1WebGrid control, you may find GridView for ASP.NET AJAX to both be
very familiar and different. While GridView for ASP.NET AJAX includes all the functionality of WebGrid for
ASP.NET, some features were added and several object model changes were made to ensure compatibility with
the standard Microsoft GridView control.
Key Differences
C1GridView is in the C1.Web.UI.Controls.C1GridView namespace.
C1GridView requires that a ScriptManager control be included on the page.
Many C1WebGrid properties, events, classes, and enumerators have been renamed or removed in
C1GridView. For example: the Items collection in C1WebGrid has been renamed to Rows in
C1GridView. This means that most places where "Item" appears in code will need to be changed to
"Row". For details of differences, see Renamed Members (page 21) and Removed Members (page 25).
New Features
Several new features were added to C1GridView, including Visual Styles (page 47), advanced scrolling, and
filtering (page 55). Several types and class members were added to support these new features. For more
information, see New Members (page 23).
Column Changes
Three new column types include: C1CheckBoxField, C1RowHeaderField, and C1ImageField. C1CheckBoxFields
can be bound to Boolean data fields for a nicer appearance and easier editing through the use of check boxes.
C1ImageField can easily display images from databound URL addresses.
The base type C1Column has been removed in C1GridView and replaced with the C1Field class.
C1CommandField replaced C1EditCommandColumn. Note that when converting from
C1EditCommandColumn to C1CommandField, you will need to set ShowEditButton to True.
Renamed Members
The tables below note some of the classes and members that were changed, to better enable you to convert your
projects to using the C1GridView control.
Classes and Enumerators
The following Classes and Enumerators in C1WebGrid have been renamed in C1GridView:

ForeColor
HScrollbarStyle*
ImageGroup+
ImageSortAscending+
ImageSortDescending+
ImageUngroup+
VScrollBarStyle*
* HScrollBarStyle and VScrollBarStyle were used in C1WebGrid to set scrollbar settings. C1GridView has a new
ScrollSettings class which handles everything C1WebGrid could do and more. To simply turn scroll bars on set
the ScrollSettings.ScrollMode property to ScrollBar. To specify orientation set ScrollSettings.ScrollOrientation
to Both, Horizontal, or Vertical.
+ The Image file paths required for C1WebGrid are no longer required for C1GridView as the images are built-in
by default and can be customized using a CSS theme.
The remaining properties that were removed are all styling properties that should now be set on a deeper level in
the control. For example, to set a background color you could set the RowStyle.BackColor property.
Key Features
In addition to the standard Microsoft GridView features, ComponentOne GridView for ASP.NET AJAX
includes advanced features that enable developers to build intuitive, professional-looking Web applications quickly
and easily:
Built-in AJAX Support
Reload your grid on demand with C1GridView's built-in AJAX support. With GridView for ASP.NET
AJAX, editing, paging, and sorting, and more can be handled through callbacks with partial page
refreshing. For more information, see Using AJAX (page 57) and Updating the Grid with AJAX (page
92).
Customized Grid Formatting
Intuitive formatting allows the developer to automatically customize any grid including creating columns,
displaying borders and gridlines, allowing editing within the grid, customizing sorting data and much
more.
Built-in Visual Styles
Style your grid application with built-in Office 2007 and Vista visual style themes and the ability to
completely customize your own theme. See Visual Styles (page 47) for more information.
CSS Styling
GridView for ASP.NET AJAX includes CSS supported styling so that you can use cascading style sheets
to easily style the C1GridView control to match the design of your current Web site.
Microsoft GridView Compatibility
GridView for ASP.NET AJAX is completely compatible with the standard Microsoft GridView control
so that you can easily convert your existing projects.
26
33. Customized Paging
You can determine how to display C1GridView data on multiple pages and how the pagers appear. Pagers
can be displayed numerically, as Next and Previous buttons or you can create your own style. See Paging
(page 56) and Creating a Pageable Grid (page 87) for more information.
Outlook-style grid, run-time features
You can implement interactive run-time features such as Outlook-style grouping, which allows you to
drag and drop a column to group on that column. For an example, see Adding Outlook-Style Grouping
(page 86).
Grouping with Aggregates
You can group data, create trees with expandable and collapsible nodes, and automatically calculate data
aggregates to be placed in the group header and footer rows. See Grouping (page 51) and Using
Aggregates and Grouping (page 84) for more information.
Built-In Filtering
C1GridView supports a built-in, data-entry row below the column headers for custom end-user operations
such as searching and filtering records. For more information, see Filtering (page 55).
Row Merging
The RowMerge property allows you to merge rows containing identical text. This feature can be used to
create a neat and well-organized grid. See Merging Rows (page 84) for an example.
ValueLists
By creating a ValueList dictionary and setting the ValueList property, you can replace the text appearing
in a grid with your own. For an example, see Customizing Columns Using ValueLists (page 66).
Client-Side Scrolling
The ScrollSettings property of C1GridView allows you to create a client-side grid that supports both
horizontal and vertical scrolling. You can determine whether your columns and rows are fixed to the grid
when it is scrolled using the Fixed property of the C1BaseField and the C1GridViewRow classes,
respectively. See Using Client-Side Scrolling (page 89) for more information.
Advanced Scrolling
C1GridView supports advanced scrolling features, such as buttons and automatic scrolling when the user
hovers near the edge of the grid, as well as standard scroll bars in either direction.
Browser Support
GridView for ASP.NET AJAX includes support for Internet Explorer (6.0 or later), Firefox (2 or later),
and Safari Web browsers.
Template Support
You can easily create timesaving grid templates with the same look and feel that can be used throughout a
project.
Client-Side Script
GridView for ASP.NET AJAX's client side functionality is provided by JavaScript included in the
product.
C1Input for ASP.NET AJAX Integration
Attach ComponentOne Input for ASP.NET AJAX controls to Edit Templates to enhance data entry.
Column Control Integration

34. Easily display check boxes, list boxes, buttons, and images in a column. See Adding Controls to a Column
(page 73) for more information.
XHTML Compliant
C1GridView provides complete XHTML compliance. The output that is generated is fully XHTML 1.1
compliant.
Samples and Task-Based Help
GridView for ASP.NET AJAX includes sample projects and task-based help to give you a better
understanding of how GridView for ASP.NET AJAX works.
The sample projects (page 59) demonstrate the techniques for using groups and aggregates,
customizing columns and pagers, and sorting and editing data.
The task-based help topics walk you step-by-step through specific tasks, such as binding C1GridView
to a data source, merging rows, and adding a column. For additional information, see GridView for
ASP.NET AJAX Task-Based Help (page 59).
Try running the projects, examining the code, and experimenting with your own modifications. Running
the samples and using the task-based help is the best and quickest way to realize the full potential of the
C1GridView control. You'll find that GridView for ASP.NET AJAX is very easy to use, and it enables
you to create powerful applications.
