DragEventHandler

  • The corresponding bubbling event is DragLeave.

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

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