Chan,
Make sure the event is wired up. If you're using VB.NET check for the
Handles keyword and the event name at the end of the method declaration.
If you're using C# check the form designer generated code and see if the
Control.AfterUpdate += new AfterUpdateEvent(method name) line is in there.
Also, make sure you're using the right control as the CheckBox doesn't have
an AfterUpdate event.
Thanks! Robert Gruen
