The event enables the drag source to determine whether the drag-and-drop operation should be canceled.
This event creates an alias for the DragDrop::QueryContinueDrag attached event for this class, so that is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the event are attached to the underlying DragDrop::QueryContinueDrag attached event and receive the same event data instance.
