.net 合并GridView中某列相同信息的行(方法2)

合并GridView中某列相同信息的行的方法：

 /// <summary>
    ///  合并1、2、3、4、5、6、7列 
    /// </summary>
    private void gvRender(GridView GridView1)
    {
        int i = 0, j = 0;
        int rowSpanNum = 1;//暂时默认合并行为1行
        string mystr; //用于与下一行对比
        //预读入第一行
        if (GridView1.Rows.Count>1)
        {
            mystr = GridView1.Rows[i].Cells[j+1].Text;
            //从第一行到最后一行
            while (i < GridView1.Rows.Count - 1)
            {
                //探索一个合并单元格  
                for (++i; i < GridView1.Rows.Count; i++)
                {
                    if (mystr == GridView1.Rows[i].Cells[j+1].Text)
                    {
                        //遇到相同行，1 隐藏该行；2 合并行数加一

                        // 1  
                       // GridView1.Rows[i].Cells[j + 0].Visible = false;

                        GridView1.Rows[i].Cells[j + 7].Visible = false;
                        // 2   
                        rowSpanNum++;
                    }
                    else
                    {
                        //没有相同行，1 刷新预读比较行；2 回写前面的合并行信息；3 重置合并行为1；4 完成一次合并             

                        // 1
                        mystr = GridView1.Rows[i].Cells[j+1].Text;

                GridView1.Rows[GridView1.Rows.Count - rowSpanNum].Cells[7].RowSpan = rowSpanNum;
            }
        }
    }

注意：本方法不支持gridview模板列,如下：

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