Comments

The OnDragEnter method raises the DragEnter event.

Raising an event invokes the event handler through a delegate.

The OnDragEnter 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.

When overriding OnDragEnter in a derived class, make sure to call the base class's OnDragEnter method so that registered delegates receive the event.
