GridView合并相同内容后的分页怎么写的

Question

 public static void Gridview_RowSpan(System.Web.UI.WebControls.GridView gv)
    {
        //合并单元格
        for (int i = 0; i < gv.Rows.Count - 1; i++)
        {
            int colnum = 1;
            int j;
            for (j = i + 1; j < gv.Rows.Count; j++)
            {
                if (gv.Rows[i].Cells[0].Text == gv.Rows[j].Cells[0].Text)
                {
                    colnum++;
                    gv.Rows[i].Cells[0].RowSpan = colnum;
                    gv.Rows[j].Cells[0].Visible = false;
                    gv.Rows[i].Cells[1].RowSpan = colnum;
                    gv.Rows[j].Cells[1].Visible = false;
                    gv.Rows[i].Cells[2].RowSpan = colnum;
                    gv.Rows[j].Cells[2].Visible = false;
                    gv.Rows[i].Cells[3].RowSpan = colnum;
                    gv.Rows[j].Cells[3].Visible = false;
                    gv.Rows[i].Cells[4].RowSpan = colnum;
                    gv.Rows[j].Cells[4].Visible = false;
                    gv.Rows[i].Cells[5].RowSpan = colnum;
                    gv.Rows[j].Cells[5].Visible = false;
                    gv.Rows[i].Cells[6].RowSpan = colnum;
                    gv.Rows[j].Cells[6].Visible = false;
                    gv.Rows[i].Cells[7].RowSpan = colnum;
                    gv.Rows[j].Cells[7].Visible = false;
                    gv.Rows[i].Cells[8].RowSpan = colnum;
                    gv.Rows[j].Cells[8].Visible = false;
                }
                else
                    break;
            }
            i = j - 1;
        }用上面的函数合并内容相同的
但是如果分页时就无法合并了，得怎么实现的

接着要实现分页得怎么写的

Answer 2

GridView合并相同内容 这一般是做报表,合并后建议就不要分页了如果分页就不要合并相同内容,因为相同的内容有可能会分布在两页上,甚至多页上,你就不好控制了

Answer 3

其实合并只是合并到一个table中，分页还是绑定这个table作为数据源就可以了！
这个问题其实很简单，道理是一样的

Answer 4

把数据读到datatable里面
用datatable作为数据源就可以了啊
这样其他的分页代码都不用改的
