Reordering Nodes
To reorder nodes in the View, drag the selected node or its indicator to the target position. You can also drag multiple nodes simultaneously in this manner, if the multi-select feature is enabled (the tree list’s OptionsSelection.MultiSelect option is active). This type of reordering can only be performed within the same nesting level.
Notes
Node dragging is enabled if the tree list’s OnDragOver event is handled (at least, an empty implementation of the event handler is provided).
