Delegate

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.
