Gets a value that indicates whether the Silverlight plug-in allows hosted content or its runtime to access the HTML DOM.
Assembly: System.Windows (in System.Windows.dll)
This property gets its value from the Silverlight plug-in configuration. For more information, see How to: Add Silverlight to a Web Page by Using HTML.
When this property is false, the HTML DOM bridge APIs are disabled. For more information about the bridge APIs, see HTML Bridge: Interaction Between HTML and Managed Code.
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;
