// Register
event_token DragItemsStarting(DragItemsStartingEventHandler const& handler) const;

Remarks

This event occurs when you start a drag-and-drop operation, including when you perform a reorder operation by drag-and-drop. When you perform custom actions as a result of a drag-and-drop operation, you typically listen to this event and provide more data using the DragItemsStartingEventArgs.Data property.

You can inspect the items being dragged by checking the DragItemsStartingEventArgs.Items property.

You can cancel the drag operation by setting the DragItemsStartingEventArgs.Cancel property to true.
