NodeDrop
When a Node is dropped onto another Node, between other Nodes or onto an HTML element the NodeDrop event fires. The RadTreeNodeDragDropEventArgs provides properties for the source and destination Nodes:
SourceDragNode: The Node being dropped.
DestDragNode: The Node being dropped onto.
DraggedNodes: A collection of RadTreeNodes that are being dragged. This could be useful when MultipleSelect is True.
DropPosition: Indicates the relationship of the Nodes being dropped and will be a RadTreeViewDropPosition enumeration value Above, Below or Over.
HtmlElementID: The ID of the HTML element that the Node is being dropped onto.
See Drag and Drop Overview for more information.
