DragEventHandler

  • The corresponding bubbling event is DragEnter.

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

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