Notes to Inheritors

The implementation of the FilterControl method returns true in all cases. Classes that derive from the ControlIDConverter override this method to provide their own filtering mechanism. For example, the AssociatedControlConverter class overrides the FilterControl method and returns true only if the control is a Web server control.
