Content.IsFullScreen Property
Gets or sets a value that indicates whether the Silverlight plug-in is displaying in full-screen mode.
Namespace: System.Windows.Interop
Assembly: System.Windows (in System.Windows.dll)
Property Value
Type: System.Booleantrue if the Silverlight plug-in displays as a full-screen plug-in. false if the Silverlight plug-in displays as an embedded plug-in.
You can set this property only in response to a user-initiated action except in trusted applications. In trusted applications, you can enter full-screen mode in (for example) a Application.Startup or FrameworkElement.Loaded event handler. However, you must do so by setting the IsFullScreen property in a delegate passed to the Dispatcher.BeginInvoke method.
For more information, see Full-Screen Support.

For best performance, when your application goes into full screen, hide or disconnect from the tree all of the objects that are not being rendered in full-screen mode. You can hide an object by setting its Visibility property to Collapsed. |
The following code example demonstrates how to use this property.
Page rootPage = new Page(); private void Application_Startup(object sender, StartupEventArgs e) { this.RootVisual = rootPage; rootPage.LayoutRoot.MouseLeftButtonDown += delegate(Object s, MouseButtonEventArgs args) { this.Host.Content.IsFullScreen = !this.Host.Content.IsFullScreen; }; this.Host.Content.FullScreenChanged += new EventHandler(DisplaySizeInformation); this.Host.Content.Resized += new EventHandler(DisplaySizeInformation); } private void DisplaySizeInformation(Object sender, EventArgs e) { String message = String.Format( "ActualWidth={0}, ActualHeight={1}", this.Host.Content.ActualWidth, this.Host.Content.ActualHeight); rootPage.LayoutRoot.Children.Clear(); rootPage.LayoutRoot.Children.Add( new TextBlock { Text = message }); }
