The data for the event.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnColumnHeaderDragDelta 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 OnColumnHeaderDragDelta in a derived class, be sure to call the base class’s OnColumnHeaderDragDelta method so that registered delegates receive the event.
