OnThreadException misses exceptions

Hi

I have in my program.cs code the followning line:

Application.ThreadException += new
ThreadExceptionEventHandler(eh.OnThreadException);

It has been working fine, catching all exceptions that is thrown, and not
caught anywhere else in the application. Now, I have a case where it does
not catch an exception! When a grid is filled with data, the DataTable event
RowChanged is triggered, in that event, an exception is raised. The IDE
stops and shows the exception, but then it just keeps executing like nothing
happened. The flow is not interrupted, and the global exception hander is
not called!! Could anyone explain this behaviour. It all seems to happen in
the same thread.

regards

Carl

Exception that happen inside RowChanged are swallowed (handled without
action), so they do not become unhandled Exceptions.

Did you by any chance change Debugger settings to "break into debugger when
exception is throw" instead of only "break into debugger when exception
isn't handled" ?

HTH,

That explains it! Strange that MS have chosen to swallow the exception
though.

Thanks for your help.
