Question

具体是什么意思？ 将news_title作为标题行？ 

Answer 1

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 {
        if (e.Row.RowType == DataControlRowType.Header)
        {
              //执行代码
        }    
 }

Answer 2

是不是要多个表头?
  是多个表头的话可以看一看这个.  //产生多表头
    protected void gdData_RowCreated(object sender, GridViewRowEventArgs e)
    {
        DataTable result = new DataTable();//
        if (CategorySelect.SelectedItem.Text == "按工厂出货")
        {
            result = Cache[CategoryStat.TypeOfSelect.按工厂分统计.ToString()] as DataTable;
        }
      
         switch (e.Row.RowType)
        {
           case DataControlRowType.Header:
                 TableCellCollection header = e.Row.Cells;
                 header.Clear();                 header.Add(new TableHeaderCell());
                  header[0].Attributes.Add("colspan", result.Columns.Count.ToString());
                 header[0].Text = "<center><strong>发货--按工厂分统计信息表(点击统计数据可以察看相关按工厂分统计信息)</strong></center></th></tr>";
                 header.Add(new TableHeaderCell());
                 header[1].Text = ("当日发货情况");
                 String[] machines=null;
                 Hashtable ht = this.calMachineColSpanNums(out machines);//返回父机型的顺序数组;
                 int i =2;
                 foreach (String machine  in machines)//
                 {
                     if (!String.IsNullOrEmpty(machine))
                     {
                         foreach (String key in ht.Keys)
                         {
                             if (key.Equals(machine))
                             {
                                 header.Add(new TableHeaderCell());
                                 header[i].Attributes.Add("colspan", ht[key].ToString());

                                     break;
                                
                             }
                         }
                     }
                 }
                  header.Add(new TableHeaderCell());

                      }
                      else                      {
                          header[i++].Text = (colu.ColumnName);
                      }
                  }
               
                  break;
