Remarks
If the DragNodesMode property is set to None, node drag-and-drop is disabled in the current Tree List control. Set the DragNodesMode property to Single or Multiple to enable single or multiple node drag-and-drop. When activating multiple node drag-and-drop, ensure that multiple node selection is enabled (see TreeListOptionsSelection.MultiSelect).
To insert a node prior to another node, by default, an end-user needs to hold the SHIFT key down while dragging. If the TreeListOptionsDragAndDrop.DropNodesMode property is set to Advanced, the SHIFT key needn’t be pressed. To insert a node above another node, an end-user should hover the dragged node over the upper half of the target node. When dragging-and-dropping over the lower half of the target node, the dragged node will be inserted as a child of the target node.
To copy the dragged node (instead of a move operation), hold the CTRL key down. Nodes can be copied only if the TreeListOptionsDragAndDrop.CanCloneNodesOnDrop option is set to true.
