Implements
IDropTarget::OnDragOver(DragEventArgs^)Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The IDropTarget::OnDragOver 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 IDropTarget::OnDragOver in a derived class, be sure to call the base class’s IDropTarget::OnDragOver method so that registered delegates receive the event.
