  • 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
  • <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.

    • 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
    • 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
  • <Grid/>
  • <Canvas/>
  • <StackPanel/>
  • <StackPanel/>
    • Silverlight supports six shapes

      • DownloadProgressChanged and other events
    • WMV1/2/3/A/VC1, WMA, and MP3
  • TranslateTransform RotateTransform SkewTransform ScaleTransform
    • 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

    • Can be scoped globally or locally
    • Combine styles and templates to “stylize” controls with custom visual trees
    • 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
