This example shows how to change the tooltip when hovering a drop target.
Although you can change tooltip in any of drag drop events, it is recommended to change the tooltip during the DragEnter event, which is raised when the current drag drop process is entering a recognized drop target.
The following code shows how to change the tooltip at DragEnter event.

All drag-drop events are built on routed event architecture including the DragEnterEvent. To learn more about routed event, see Routed Events overview. |
