            sftTree1.Initializing = false;
        }

        // ItemClick event
        private void sftTree1_ItemClick(object sender, ItemClickEventArgs e) {
            Debug.Write("** ItemClick");
            int itemIndex = -1;
            if (e.Item != null) 
                itemIndex = e.Item.VisibleIndex;
            if (itemIndex >= 0)
                Debug.Write(" Row " + itemIndex.ToString());
            int colIndex = -1;
            if (e.Cell != null)
                colIndex = e.Cell.ColumnIndex;
