DragEventHandler

  • The corresponding tunneling event is PreviewDragEnter.

  • Override OnDragEnter to implement class handling for this event in derived classes.

This event creates an alias for the DragDrop.DragEnter attached event for this class, so that UIElement.DragEnter is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the DragEnter event are attached to the underlying DragDrop.DragEnter attached event and receive the same event data instance.
