方法：

public GridViewRow GetCurrentRow(Object CtrlInCell)
        {
            Control Ctrl = (Control)CtrlInCell;
            int Count = 0;
            while ((Ctrl = Ctrl.Parent) != null && Count < 5)
            {
                if (Ctrl.GetType().Name.IndexOf("Cell") >= 0)
                {
                    return (GridViewRow)Ctrl.Parent;
                }
                Count++;
            }
            return null;
        }
