dragEvent
DragEventArgs

A DragEventArgs that contains the event data.

Implements

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnDragDrop 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 OnDragDrop(DragEventArgs) in a derived class, be sure to call the base class' OnDragDrop(DragEventArgs) method so that registered delegates receive the event.
