     && e.HitInfo.InItem
     && e.HitInfo.Item.Item is BarButtonItem)
    {
         this.popupMenu.ShowPopup(Control.MousePosition);
    }
    //右键位置：在barSubItem中的barButtonItem上
    else if (e.Link != null

                {
                    TreeListNode node = treeList1.FindNodeByID(hi.Node.Id);
                    treeList1.FocusedNode = node;
