GridView.DragObjectDrop Event

Fires immediately after a drag and drop operation on a column header or band header has been completed.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v18.2.dll

Declaration

C#

[DXCategory("DragDrop")]
public event DragObjectDropEventHandler DragObjectDrop

VB.NET

<DXCategory("DragDrop")>
Public Event DragObjectDrop As DragObjectDropEventHandler

Event Data

The DragObjectDrop event's data class is DragObjectDropEventArgs. The following properties provide information specific to this event:

Property	Description
Canceled	Gets whether the dragged header has been dropped successfully.
DragObject	Gets the column or band whose header has been dropped.
DropInfo	Gets an object providing information about drop position.

Remarks

Handle the DragObjectDrop event to perform actions when end-users finish dragging column and band headers. This can be used, for instance, to do any cleanup necessary after handling the GridView.DragObjectStart event.

The event serves only as a notification that the operation has been completed. To control whether headers can be dropped at a particular position, handle the GridView.DragObjectOver event.

For general information on handling header dragging, see the GridView.DragObjectStart topic.
