合并GridView中某列相同信息的行（单元格）

合并GridView中某列相同信息的行（单元格），如图：

                                        
                                     
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 }

如果多列要求合并时，可作适当修改。
