Occurs when there is a change in the keyboard or mouse button state during a drag-and-drop operation.
Assembly: PresentationCore (in PresentationCore.dll)
Theevent 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 UIElement3D 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.
