【求助】GridView 单元格合并问题！！

Question

我想把某一列相同内容的合并，但是却不能合并，相邻内容数据的可以合并，不相邻的不能合并，出现下面的问题。http://hi.csdn.net/attachment/201002/2/1403_1265082496T7Ov.jpg代码：
        protected void gvIntendanceNet_DataBound(object sender, EventArgs e)
        {
            int row = 0;
            for (int i = 1; i < gvIntendanceNet.Rows.Count; i++)
            {
                if (gvIntendanceNet.Rows[i].Cells[1].Text == gvIntendanceNet.Rows[i - 1].Cells[1].Text)
                {
                    if (gvIntendanceNet.Rows[row].Cells[1].RowSpan == 0)                        gvIntendanceNet.Rows[row].Cells[1].RowSpan++;
                    gvIntendanceNet.Rows[row].Cells[1].RowSpan++;
                    gvIntendanceNet.Rows[i].Cells[1].Visible = false;                }
                else
                {
                    row = i;
                }
            }        }为什么呢？

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; 
                    } 
                } 
            } 
        }

给lZ 贴一下 我做的分页吧！··希望给LZ 带来帮助
 //合并单元格
 public void GroupRows()
{
          int i = 0, rowSpanNum = 1;
            //需要合并的列
            int _CD_C = Convert.ToInt32(ColsNo._CD_C);//单号
 while (i < this.GridView1.Rows.Count - 1)
{
GridViewRow gvr = GridView1.Rows[i];
for (++i; i < this.GridView1.Rows.Count; i++)
{
GridViewRow gvrNext = GridView1.Rows[i];
if (gvr.Cells[_CD_C].Text == gvrNext.Cells[_CD_C].Text)
{
         //单号
          gvrNext.Cells[Convert.ToInt32(ColsNo._CD)].Visible = false;
         rowSpanNum++;
}
 else
{ 
   //单元格跨越的行数
       //单号
       gvr.Cells[Convert.ToInt32(ColsNo._CD)].RowSpan = rowSpanNum;
          rowSpanNum = 1;
          break;
}
 if (i == GridView1.Rows.Count - 1)
{
           //单号
            gvr.Cells[Convert.ToInt32(ColsNo._CD)].RowSpan = rowSpanNum;
}
}
}
}
括号LZ 自己对对 我在这里面编辑部习惯..
ColsNo  我是对gridview定义的一个枚举  用来记住gridview列的位置
