The document discusses Crystal Reports, a reporting tool used to display data in a presentable manner. Crystal Reports requires database drivers to connect to data sources and supports two data access methods: the pull model, which retrieves data directly from the data source, and the push model, where the developer retrieves data and caches it in a dataset. Crystal Reports can be created manually, with a wizard, or from an existing report, and its presentation quality enhanced with charts and cross-tab objects. It can be hosted in a Windows application using the CrystalReportViewer control bound to a report.

Introducing Crystal Reports
Crystal Reports is the standard reporting tool for Visual
Studio .NET, used to display data in a presentable manner.
Creating a Crystal Reports requires minimal coding
because it is created in a designer interface.

Data Access Through Crystal Reports
Crystal Reports requires database drivers to connect to a
data source for accessing data.
Crystal Reports in Visual C# support methods to access
data from a data source. These methods are:
– The Pull Model In this model data is accessed
– The Push Model from the data source and the
database driver directly retrieves
data from the data source.

Data Access Through Crystal Reports (Contd.)
Crystal Reports requires database drivers to connect to a
data source for accessing data.
Crystal Reports in Visual C# support methods to access
data from a data source. These methods are:
– The Pull Model
– The Push Model In this model the developer writes code to
connect to the data source and retrieves
data from it. The data from the data
source is cached in a dataset and multiple
Crystal Reports access the data from the
dataset.

Creating Crystal Reports
You can create Crystal Reports by using any one of the
following methods:
Manually
Using Standard Report Wizard
From an existing report
Let us see how the reports can be created using these
methods.

Implementing CrystalReportViewer Control in .NET Applications
The CystalReportViewer is present as a control in the
Toolbox.
It can be inserted into a Windows application by dragging
the CystalReportViewer control from the Toolbox into the
form.
Interaction between the CrystalReportViewer control and
other controls on the Windows Form can be created by
handling the events of the Windows Form controls and the
CrystalReportViewer control.

Hosting Crystal Report
After the Crystal Report has been created, it needs to be
hosted in the Windows application so that the user can view
the Crystal Reports at run time.
The two steps for hosting a Crystal Report in a Windows
application are:
1. Adding a Windows Forms Viewer to the Windows Form.
2. Binding the CrystalReportViewer control to the created Crystal
Reports.
Let us see how the Crystal Report can be hosted in a
Windows application.

Summary
In this session, you learned that:
Crystal Reports is the standard reporting tool for Visual
Studio .NET that is used to display data of presentation quality.
Crystal Reports use database drivers to connect with the data
source for accessing data.
Crystal Reports in VC# .NET supports two methods to access
data from a data source:
• The Pull model
• The Push model
The presentation quality of a Crystal Reports can be enhanced
by adding the following components to the Crystal Reports:
• Chart
• Cross-tab objects
– Crystal Reports can be hosted in a Windows Form by using the
Windows Forms Viewer.
