Type	Description
Image	An Image object that specifies a preview of dragged data elements.

Remarks

During a drag-and-drop operation, the Behavior Manager shows a preview of dragged data elements near the mouse pointer. You can use the DragDropManager.PreviewShowMode property to disable the preview image or enable it for target controls only.

If this setting is enabled, you can disable a particular control’s preview with the DragDropBehavior.Properties.PreviewVisible property.

To customize the preview image, use the following options:

• the PreviewImage event argument in a DragDropManager.QueryDragPreviewImage event handler

• the PreviewImage event argument in a DragDropEvents.BeginDragDrop event handler
