/** @event */ public void add_UnhandledException (DispatcherUnhandledExceptionEventHandler value) /** @event */ public void remove_UnhandledException (DispatcherUnhandledExceptionEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
This event is raised when an exception that was thrown during execution of a delegate by way of Invoke or BeginInvoke is uncaught.
A handler can mark the exception as handled which will prevent the internal exception handler from being called.
Event handlers for this event must be written with care to avoid creating secondary exceptions and to catch any that occur. It is recommended to avoid allocating memory or doing any resource intensive operations in the handler.
The UnhandledExceptionFilter event provides a means to not raise the UnhandledException event. The UnhandledExceptionFilter event is raised first, and If RequestCatch on the DispatcherUnhandledExceptionFilterEventArgs is set to false, the UnhandledException event will not be raised.
