DataGrid中怎么给模板列赋值

DataGrid中如何给模板列赋值
//.aspx--代码：

//.CS--绑定及分页代码-----------------------------------------
private void CheckBind()
{
string str = "";
str = "select * from zcsgd_t_v WHERE bmjl_tp='2' ";
DataSet ds = new DataSet();
ds = Info.Select(str, "zcsgd_t_v");

//if (ds.Tables[0].Rows.Count > 0)
//{
// Label lbl = new Label();
// for (int c = 0; c < ds.Tables[0].Rows.Count; c++)
// {
// lbl = (Label)this.dtgDj.Items[c].FindControl("lblzt");
// if (ds.Tables[0].Rows[c]["zhb_tp"].ToString() == "1")
// {
// if (ds.Tables[0].Rows[c]["sgd_stu"].ToString() == "0")//
// {
// lbl.Text = "等候审核";
// }
// else if (ds.Tables[0].Rows[c]["sgd_stu"].ToString() == "2")
// {
// lbl.Text = "被撤销";
// }

// }
// else if (ds.Tables[0].Rows[c]["zhb_tp"].ToString() == "2")
// {
// lbl.Text = "已审核";
// }
// }
//}

this.dtgDj.DataSource = ds;
this.dtgDj.DataBind();
}

protected void Button1_Click(object sender, EventArgs e)
{
//上一页
if (this.dtgDj.CurrentPageIndex != 0)
{
this.dtgDj.CurrentPageIndex = this.dtgDj.CurrentPageIndex - 1;
}
CheckBind();
}
protected void Button2_Click(object sender, EventArgs e)
{
//下一页
if (this.dtgDj.CurrentPageIndex != this.dtgDj.PageCount - 1)
{
this.dtgDj.CurrentPageIndex = this.dtgDj.CurrentPageIndex + 1;
}
CheckBind();
}
问题是这样的，屏蔽了中间那段给模板列中的Label赋值的代码后，一切正常，能实现分页。
如果运行中间那段代码，则提示错误：
异常详细信息: System.ArgumentOutOfRangeException: 索引超出范围。必须为非负值并小于集合大小。

问：有什么方法能实现模板列中Label赋值，并且能实现分页。

[解决办法]
<%# Eval("列名").ToString()%>
[解决办法]
你每次都取ds.Tables[0].Rows.Count总数，而你每页数量要少于总数，所以你遍历就要越界了
[解决办法]
感觉你的意思应该是格式化单元格内容

C# code

  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)  {      if (e.Row.RowType == DataControlRowType.DataRow)      {          if (e.Row.Cells[索引].Text == "xxx")          {              e.Row.Cells[索引].Text = "bbbbb";          }      }  }
[解决办法]
控件加个事件GridView1_RowDataBound
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         if (e.Row.Cells[zhb_tp的索引].Text == "1")
         {
             if (e.Row.Cells[sgd_stu的索引].Text == "0")
                 e.Row.Cells[索引].Text = "等待审核";
             if (e.Row.Cells[sgd_stu的索引].Text == "2")
                 e.Row.Cells[索引].Text = "被撤销";
         }
         else if (e.Row.Cells[zhb_tp的索引].Text == "2")
         {
             e.Row.Cells[索引].Text = "已审核";
         }
     }
 }

[解决办法]
datatable 中有数据么？没有的话
  for (int c = 0; c &lt; ds.Tables[0].Rows.Count; c++)
  会报越界的错误
