Controls that support the Drag-and-Drop Behavior have a default action for each stage of a drag-and-drop operation. For instance, when data elements are dragged over a control, the control calculates the insert indicator’s bounds. When data elements are dropped, the control moves or copies data elements. The following arguments allow you to invoke or suppress the default action:
The Handled property - gets or sets whether you handled the event. If the event is handled, the control does not perform the default action.
The Default() method - invokes the default action. If you call this method, the Handled property is automatically set to true.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the Handled property.
