Establishes the handler for the FullScreenChanged event that occurs whenever the FullScreen property of the Silverlight plug-in changes.
<object ...> <param name="onfullscreenchanged" value="scriptHandlerName" /> ... </object>
The FullScreenChanged event occurs whenever the Silverlight plug-in changes between embedded mode and full-screen mode:
In embedded mode, the plug-in displays in the Web browser window.
In full-screen mode, the plug-in displays on top of all other applications.
When the Silverlight plug-in displays in embedded mode, the plug-in is contained within the browser window. When the Silverlight plug-in displays in full-screen mode, the plug-in resizes to the current resolution of the display and overlays all other applications, including the browser. The following illustration show the differences between embedded mode and full-screen mode.
Silverlight does not support automatic layout of elements based on run-time size changes to the plug-in area. This means that applications have to provide logic to resize themselves appropriately when the plug-in size changes.
