Namespace:DevExpress.Utils.DragDrop
Assembly:DevExpress.Utils.v19.2.dll

Expanded Syntax

Expanded Event Data

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

The following BeginDragDropEventArgs properties provide information specific to this event.
Property Description
