The BeforeItemDrag event fires when a drag operation is initiated by an end-user. The event allows you to do the following:
- Prevent the drag operation from starting, by setting the event’s Cancel parameter to true.
- Provide a custom drag image for the drag operation with the event’s DragImage parameter. Initially, this parameter contains the default drag image, which was created from the tile being dragged.
