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.
