简单随笔——如何在gridview的页脚显示信息。。。。

 1   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
 2 
 3      {
 4         if (e.Row.RowType == DataControlRowType.DataRow)
 5         
 6         
 7         {
 8             if (e.Row.RowIndex > -1)
 9 
10             {
11              
12                 sum1 += Convert.ToDouble(e.Row.Cells[4].Text);
13                 sum2 += Convert.ToDouble(e.Row.Cells[5].Text);
14                 sum3 += Convert.ToDouble(e.Row.Cells[6].Text);
15 
16             }
17  
18         }
19         else if (e.Row.RowType == DataControlRowType.Footer)
20         {
21             e.Row.Cells[3].Text = "金额合计";
22             e.Row.Cells[4].Text = sum1.ToString();
23             e.Row.Cells[5].Text = sum2.ToString();
24             e.Row.Cells[6].Text = sum3.ToString();
25         }
