两个自己写的合并GridView 行的方法

        public void MergeRow(GridView gv, int cellNum)
        {
            int i = 0;
            int row = 0;
            foreach (KeyValuePair<string, int> kp in this.HashECR)
            {
                GridViewRow gvr = gv.Rows[i];
                gvr.Cells[cellNum].RowSpan = kp.Value;
                row = row + kp.Value;
                int next = i + 1;
                for (int j = next; j < row; j++)
                {
                    GridViewRow gvrNext = gv.Rows[j];
                    gvrNext.Cells[cellNum].Visible = false;
                }
                i = i + kp.Value;
            }
        }

public void MergeBomChangeRow(GridView gv, int cellNum)
        {
            int i = 0;
            int allrow = 0;
            while (i < gv.Rows.Count)
            {
                GridViewRow gvr = gv.Rows[i];
                int row = int.Parse(((Label)gvr.FindControl("lblRows")).Text);
                gvr.Cells[cellNum].RowSpan = row;
                for (int j = 1; j < row; j++)
                {
                    GridViewRow gvrNext = gv.Rows[j + i];
                    gvrNext.Cells[cellNum].Visible = false;
                }
                allrow = allrow + row;
                i = allrow;
            }

        }
