Content.FullScreenChanged Event

Silverlight

Occurs when the hosted Silverlight plug-in either enters or exits full-screen mode.

Namespace:  System.Windows.Interop
Assembly:  System.Windows (in System.Windows.dll)

public event EventHandler FullScreenChanged

The event does not report the state. When you handle the event, immediately check IsFullScreen.

The following code example demonstrates how to use this event.


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 });
}
