2. Where did Silverlight come from and what can it really do What is XAML and how does it aid in UI authoring What controls ship with Silverlight and how can they be styled and data-bound What functionality is available in the Silverlight Base Class Library

3. Visual Studio 2008 Silverlight 2 Runtime Microsoft Silverlight Tools for for VS2008 Other useful stuff Silverlight 2 SDK (installed with tools install) Expression Studio 2 (Blend SP1) Deep Zoom Composer Silverlight 2 Controls Source Code + Unit Tests

4. Introduction to Silverlight XAML Controls Base Class Library

5. Formerly known as "WPF/E" Microsoft's platform for rich, highly interactive Web experiences and RIAs Cross-platform (browsers and OSes) Windows, Mac OS, Linux ("Moonlight") Internet Explorer, Firefox, Safari, and more XAML-based rendering (subset of WPF XAML) Implemented as browser plug-in Quick, easy install experience

6. Silverlight 1.0 Shipped September 2007 XAML rendering and JavaScript API Silverlight 2 Shipped October 2008 XAML, .NET Framework, managed code, dynamic languages (e.g., IronPython, IronRuby)

8. Refactored version of full-size CLR Same core type system, JIT compiler, etc. COM interop, remoting, binary serialization, server GC, and other features removed CAS replaced with transparency model Multiple CLR instances per process supported Most globalization support pushed down to OS Dynamic Language Runtime (DLR) added Small footprint (< 2MB), cross-platform

9. System.Windows System.Windows.Controls System.Windows.Input System.Windows.Interop System.Windows.Media System.Windows.Shapes System.Windows.Threading System.Windows.Browser System System.Collections System.Collections.Generic System.Diagnostics System.Globalization System.IO System.IO.- IsolatedStorage System.Reflection System.Security System.Security.Cryptography System.Text System.Threading System System.Collections.Generic System.ComponentModel System.Diagnostics System.Text.RegularExpressions System.Linq System.Linq.Expressions System.Runtime.CompilerServices System.Security.Cryptography System.Xml System.XmlSchema System.Xml.Serialization

10. Web project generated by Visual Studio for testing and debugging Main project HTML test page XAML file containing global (application) resources and event handlers XAML file containing &quot;page&quot; seen by user XAP file containing application assembly, library assemblies, and resources

11. <object id=&quot;SilverlightControl&quot; data=&quot;data:application/x-silverlight&quot; type=&quot;application/x-silverlight-2-b2&quot; width=&quot;100%&quot; height=&quot;100%&quot;> <param name=&quot;source&quot; value=&quot;ClientBin/SilverLife.xap&quot; /> </object> OBJECT tag Application package Control DOM ID MIME type Control version Width and height XAP file containing application assembly, resources, etc.

12. <Canvas Width=&quot;300&quot; Height=&quot;300&quot; xmlns=&quot;http://schemas.microsoft.com/client/2007&quot; xmlns:x=&quot;http://schemas.microsoft.com/winfx/2006/xaml&quot;> <Ellipse Canvas.Left=&quot;20&quot; Canvas.Top=&quot;20&quot; Height=&quot;200&quot; Width=&quot;200&quot; Stroke=&quot;Black&quot; StrokeThickness=&quot;10&quot; Fill=&quot;Yellow&quot; /> <Ellipse Canvas.Left=&quot;80&quot; Canvas.Top=&quot;80&quot; Height=&quot;35&quot; Width=&quot;25&quot; Stroke=&quot;Black&quot; Fill=&quot;Black&quot; /> <Ellipse Canvas.Left=&quot;140&quot; Canvas.Top=&quot;80&quot; Height=&quot;35&quot; Width=&quot;25&quot; Stroke=&quot;Black&quot; Fill=&quot;Black&quot; /> <Path Data=&quot;M 70, 150 A 60, 60 0 0 0 170, 150&quot; Stroke=&quot;Black&quot; StrokeThickness=&quot;15&quot; StrokeStartLineCap=&quot;Round&quot; StrokeEndLineCap=&quot;Round&quot; /> </Canvas>

13. XAML objects fire events Canvases and UI objects fire Loaded events and mouse events (e.g., MouseLeftButtonDown) Root canvas also fires keyboard events Other objects fire object-specific events Handlers can be registered declaratively or programmatically Mouse events &quot;bubble up&quot; through XAML object hierarchy

14. Layout is driven by Panel objects Every page has a root Grid object Page can contain additional Grids or Canvases Panels are a containers for other UI elements Grids, StackPanel, Canvas are types of panels All units measured in logical pixels

15. <Grid/>

16. <Canvas/>

17. <StackPanel/>

18. <StackPanel/>

19. Silverlight supports six shapes Rectangle Ellipse Polygon Line PolyLine Path

20. Audio/video playback in a box Progressive downloads and streaming Robust API provides basis for rich UIs Play, Pause, Stop, and other methods Position, Volume, and other properties DownloadProgressChanged and other events WMV1/2/3/A/VC1, WMA, and MP3

21. TranslateTransform RotateTransform SkewTransform ScaleTransform

22. Animations are created by varying properties of XAML objects over time From/To animations vary properties linearly Key-frame animations use discrete steps Animation objects define animations DoubleAnimation[UsingKeyFrames] ColorAnimation[UsingKeyFrames] PointAnimation[UsingKeyFrames] StoryBoard objects hold animation objects

24. Created a smiley face object using Expression Blend Applied an animation to the smiley face object Added some event handling to the smiley face using Visual Studio

25. More than 20 built-in controls Canvas, StackPanel, Grid, and GridSplitter Button, CheckBox, HyperlinkButton, RepeatButton, RadioButton, and ToggleButton TextBox, ListBox, and DataGrid TabControl, Slider, and MultiScaleImage Border, Calendar, DatePicker, and more! Support styles, templates, and data binding

26. FrameworkElement ButtonBase ContentControl Control Button HyperlinkButton RepeatButton ToggleButton CheckBox RadioButton ScrollViewer Calendar DataGrid DatePicker GridSplitter TextBox RangeBase ItemsControl ListBox Slider Scrollbar TabControl

27. FrameworkElement Canvas Panel Grid StackPanel Border Image MediaElement MultiScaleImage TextBlock InkPresenter

28. Redefine a control’s entire visual tree Perform extreme customization without changing basic behavior of control Exposed through control's Template property (inherited from Control base class) Use {TemplateBinding} to flow property values from control to template Use ContentPresenter and ItemsPresenter to flow content and items to template

29. Styles provide level of indirection between visual properties and their values Define style as XAML resource Apply style using {StaticResource} markup extension Can be scoped globally or locally Combine styles and templates to “stylize” controls with custom visual trees

30. Permits properties of one object to be bound to properties of another Target property must be DependencyProperty Source property can be any type of property Source can be a collection if target supports binding to collections {Binding} markup extension provides declarative support for data binding

32. Added a ListBox control to our XAML Applied a DataTemplate to the ListBox Data-bound our new ListBox control to a generic list of user objects Applied 2 different styles to our data-bound ListBox

33. System.Windows.Browser namespace contains classes for accessing browser DOM HtmlPage, HtmlWindow, and others Managed -> unmanaged Access DOM from managed code Call JavaScript functions from managed code Unmanaged -> managed Call managed code from JavaScript Process DOM events with managed code

34. General-purpose file I/O not permitted OpenFileDialog can be used to open files User interaction constitutes permission needed to safely open files No SaveFileDialog yet Isolated storage can be used to persist data locally subject to quotas Quote is initially set to 1MB per domain but can be increased

35. Silverlight 2 has rich networking support SOAP/XML Web services via WCF proxies HTTP services (POX, REST, RSS, ATOM) via HttpWebRequest and WebClient classes Socket support, asset downloads over HTTP, syndication classes, and more Cross-domain access supported using Flash-compatible or Silverlight XML policy files

36. Allowed if target domain has XML policy file in place permitting calls from other domains Crossdomain.xml – Requires domain=&quot;*&quot; allowing calls from any domain Clientaccesspolicy.xml – Can restrict access to certain domains only Policy file must be located at domain root

37. Delegate-based HTTP networking API Supports asynchronous operation only Provides control over wire format GET/POST/PUT/DELETE (REST) Customization of HTTP headers Completion methods called on background threads

38. Event-based HTTP networking API Commonly used to download assets DownloadStringAsync - String OpenReadAsync – Stream (binary) Can also be used to perform uploads Fires progress and completion events and supports cancellation of pending requests Event handlers execute on UI thread

40. Added a DataGrid control to our XAML Opened and parsed a local XML file Downloaded and parsed an RSS feed Data-bound our parsed data to the added DataGrid control

41. Microsoft Silverlight is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of media experiences and rich interactive applications for the Web By using Expression Studio and Visual Studio, designers and developers can collaborate more effectively using the skills they have today to light up the Web of tomorrow
