Events the Container Provides for Your Control

See Also

The container's extender object may provide events for the benefit of developers using your control. If your control is used with Visual Basic, the user of your control gets four such events without any work on your part: GotFocus, LostFocus, DragOver, and DragDrop.

You don't need to be concerned with extender events. They are invisible to your control, and you cannot put code in their event procedures.
