TileView.BeforeItemDrag Event

Fires when a tile drag operation is about to be started. Allows you to provide a drag image, or to cancel the operation.

Namespace:DevExpress.XtraGrid.Views.Tile
Assembly:DevExpress.XtraGrid.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type BeforeItemDragEventArgs containing data related to this event.

The following BeforeItemDragEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets a value indicating whether the event should be canceled.
DragImage Gets or sets the image that represents the tile during the drag-and-drop operation.
RowHandle Gets the row handle that identifies the current tile.

Expanded Remarks

The built-in tile drag-and-drop feature can be enabled with the TileViewOptionsDragDrop.AllowDrag setting (available from the OptionsDragDrop property). Using the following events, you can customize and handle built-in drag-and-drop operations:

  • BeforeItemDrag - Fires when a tile drag operation is about to be started. Allows you to provide a drag image, or to cancel the operation.
  • BeforeItemDrop - Fires when a tile drop operation is initiated.
  • ItemDrop - Fires after a tile drop operation has been completed.
The BeforeItemDrag event fires when a drag operation is initiated by an end-user. The event allows you to do the following:
  • Prevent the drag operation from starting, by setting the event's Cancel parameter to true.
  • Provide a custom drag image for the drag operation with the event's DragImage parameter. Initially, this parameter contains the default drag image, which was created from the tile being dragged.
