合并GridView中某列相同信息的行（单元格）

解决方法如下（写在公共模块里，定义为静态方法方便调用）：

1 /// <summary>

2 /// 合并GridView中某列相同信息的行（单元格）

3 /// </summary>

4 /// <param name="GridView1">GridView</param>

5 /// <param name="cellNum">第几列</param>

6 public static void GroupRows(GridView GridView1, int cellNum)

7 {

8 int i = 0, rowSpanNum = 1;

9 while (i < GridView1.Rows.Count - 1)

10 {

11 GridViewRow gvr = GridView1.Rows[i];

12

13 for (++i; i < GridView1.Rows.Count; i++)

14 {

15 GridViewRow gvrNext = GridView1.Rows[i];

16 if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)

17 {

18 gvrNext.Cells[cellNum].Visible = false;

19 rowSpanNum++;

20 }

21 else

22 {

23 gvr.Cells[cellNum].RowSpan = rowSpanNum;

24 rowSpanNum = 1;

25 break;

26 }

27

28 if (i == GridView1.Rows.Count - 1)

29 {

30 gvr.Cells[cellNum].RowSpan = rowSpanNum;

31 }

32 }

33 }

34 }
