TileContainer.StartItemDragging Event
Occurs whenever an end-user starts dragging a TileContainer‘s tile.
Namespace: DevExpress.XtraBars.Docking2010.Views.WindowsUI
Assembly: DevExpress.XtraBars.v23.2.dll
NuGet Package: DevExpress.Win.Navigation
Declaration
Event Data
The StartItemDragging event's data class is TileItemDragEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
| Item | Gets or sets a tile item that fired an event which takes the TileItemDragEventArgs object as a parameter. |
| TargetGroup | Gets the TileGroup to which a TileItem being dragged is about to be placed. |
Remarks
The StartItemDragging event is used to completely prohibit individual tiles (e.Item) from dragging. To do so, set the e.Cancel parameter to true.
The e.TargetGroup parameter is always null, since the StartItemDragging event is raised when the dragging has just begun. In order to check to which group an end-user wants to drag a tile, and if necessary, cancel this action, handle the TileContainer.EndItemDragging event instead.
