Event-Handling Subroutines
The
name of an event-handling subroutine will consist of the ID of the
control that rasied the event followed by the type of event being
handled. For example, a subroutine named btnSubmit_Click handles the
Click event of a Button control named btnSubmit.
When
a control that raises an event is not assigned an ID, the type of the
control is used instead of the ID. For example, the subroutine named
Button_Click handles the Click event of a Button control without an ID.
