Gets or sets a value that indicates whether to show the areas of the Silverlight plug-in that are being redrawn each frame.
Assembly: System.Windows (in System.Windows.dll)
The property enables a diagnostic feature that is used during development for performance-tuning your application by showing the areas of the plug-in that are being redrawn each frame. You cannot set this property during initialization. Typically you would turn this property on and off using an event handler, after the Silverlight plug-in is loaded.
The following code example demonstrates how to use this property.
// The Host object, which represents the host Silverlight plug-in. System.Windows.Interop.SilverlightHost host = Application.Current.Host; // The following code demonstrates how to use the Host object // to access other APIs in the System.Windows.Interop namespace. // The IsVersionSupported method. This method is useful when // you want to implement an upgrade experience in managed code. bool isSupported = host.IsVersionSupported("2.0.30908.0"); // Read-only properties of the Host object. System.Windows.Media.Color pluginBackground = host.Background; bool loaded = host.IsLoaded; Uri source = host.Source; // The Settings object, which represents Web browser settings. System.Windows.Interop.Settings settings = host.Settings; // Read/write properties of the Settings object. settings.EnableFrameRateCounter = true; settings.EnableRedrawRegions = true; settings.MaxFrameRate = 60; // Read-only properties of the Settings object. bool windowless = settings.Windowless; bool htmlAccessEnabled = settings.EnableHTMLAccess; // The Content object, which represents the plug-in display area. System.Windows.Interop.Content content = host.Content; // The read/write IsFullScreen property of the Content object. // See also the Content.FullScreenChanged event. bool isFullScreen = content.IsFullScreen; // Read-only properties of the Content object. These properties do // not contain meaningful values until after the Content.Resized // event occurs for the first time. double actualWidth = content.ActualWidth; double actualHeight = content.ActualHeight;
