C#

                child.RowHeader.Text = i.ToString();
            }
            sftTree2.Columns.MakeOptimal(0, false);
            sftTree2.RecalcHorizontalExtent();
            sftTree2.Initializing = false;
        }

        private void sftTree1_DragDetected(object sender, DragDetectedEventArgs e) {
            Debug.Write("sftTree1_DragDetected ");
            DumpValues(e);
            // get the current item
            if (e.Item == null) return;
            ItemClass item = e.Item;
            // don't drag headers, footers
            if (item.UsageLocation != UsageLocationEnum.items)
