When writing Silverlight TruckWars, I was trying to figure out how to create a global error handler for a page. Eventually I saw the WebApplication.Current.ApplicationUnhandledException event, which I could hook up like so:
public void Page_Loaded(object o, EventArgs e)
{
//....
WebApplication.Current.ApplicationUnhandledException +=
new EventHandler<ApplicationUnhandledExceptionEventArgs>
(Current_ApplicationUnhandledException);
}
void Current_ApplicationUnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
{
HandleError(e);
}
Note that Silverlight handles errors differently than ASP.Net. In ASP, you get the yellow error page with a detail exception message (by default). However, in Silverlight, it just stops executing your code and returns to the caller, leading to weird behavior.
