PreButtonClickedEventArgs Class

The PreButtonClickedEventArgs class includes the method that passes details of a clicked button BEFORE it is processed. It inherits from the PostButtonClickedEventArgs() method to get the basic button clicked arguments, but adds the Cancel parameter to allow the user to intercept this event for pre-processing and cancel it if necessary.
