## The `onDragDrop' callback

Event number: 34
Valid for: Any visible control

The `onDragDrop` callback is invoked for the target control when a successful drag-and-drop operation has been completed, and the user releases the mouse over the target control. (For this to happen, the `sourceformats` property of the source must be compatible with the `targetformats` property of the target).

Under Windows, it will typically be preceded by an `onDragEnter` and several `onDragOver` events. The source control will be notified by an `onDragEnd` event.

The `dragsource` property will contain the name of the control being dragged.

The event-specific parameters in ŒEV are (in index origin 1):
