DragObjectOverEventArgs is the data class for the following events:

• GridView.DragObjectOver

Remarks

The GridView.DragObjectOver event fires repeatedly while dragging a column header or band header. It enables you to identify the band or column whose header is being dragged and the header’s potential position. The DragObjectOverEventArgs class introduces the DragObjectOverEventArgs.DragObject and DragObjectOverEventArgs.DropInfo properties. The latter parameter’s Valid attribute can be used to prohibit dropping to the current position.
