Detecting unhandled exceptions in bound properties

I want report all unhandle exceptions  and shut down the WPF app. I have coded the DispatcherUnhandledException and the AppDomain.CurrentDomain.UnhandledException but my unhandled exception is not trapped by either one. The exception is happening when a binding updates to source.  It seems the exception is getting swallowed.  

Is there a way to prevent this? or should I be handling all errors?
