The OnPopUpOpening method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When overriding OnPopUpOpening in a derived class, be sure to call the base class's OnPopUpOpening method so that registered delegates receive the event.
