.net 合并GridView中某列相同信息的行（方法1）

合并GridView中某列相同信息的行的方法：

/// <summary> 
    /// 合并GridView中某列相同信息的行（单元格） 
    /// </summary> 
    /// <param name="GridView1">GridView</param> 
    /// <param name="cellNum">第几列</param> 
    public static void GroupRows(GridView GridView1, int cellNum)
    {
        int i = 0, rowSpanNum = 1;
        while (i < GridView1.Rows.Count - 1)
        {
            GridViewRow gvr = GridView1.Rows[i];
            for (++i; i < GridView1.Rows.Count; i++)
            {
                GridViewRow gvrNext = GridView1.Rows[i];
                if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)
                {
                    gvrNext.Cells[cellNum].Visible = false;
                    rowSpanNum++;
                }
                else
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                    rowSpanNum = 1;
                    break;
                }
                if (i == GridView1.Rows.Count - 1)
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                }
            }
        }
    }

方法调用：

GroupRows(SearchGrird, 0); //针对第一列进行相同数据行合并
GroupRows(SearchGrird, 1); //针对第二列进行相同数据行合并

效果图：

注意：本方法不支持gridview模板列,如下：

1 <asp:TemplateField HeaderText="序号">
2                                                 <ItemTemplate>                                               
3                                                     <%#Container.DataItemIndex+1%>
4                                                 </ItemTemplate>
5                                                  <ControlStyle Font-Underline="False" />
6                                             </asp:TemplateField>

           支持下列的写法：

 1 <asp:BoundField DataField="Name" HeaderText="病人姓名" />
