This sample demonstrates row drag-and-drop within a single Tree Grid, allowing records to be reordered and hierarchy restructured by dragging a row handle to move items above, below, top, bottom, or as a child of another row.
Enable row drag-and-drop by setting AllowRowDragAndDrop to true. In this demo, the tree column is Task Name; use its drag handle to drop items in valid targets without changing cell values.
See the drag-and-drop documentation here.
