Handling errors in Silverlight

Use the Htmlwindow.Eval method value to handle errors in Silverlight

This method is available in the System.Windows.Browser assembly.

In the Application_UnhandledException event, you can capture the Error, and throw the unhandled exception as a Javascript error.

Code:
System.Windows.Browser.HtmlPage.Window.Eval(string.Format(""My error : {0}"" , e.Exception.Message);
