效果图如下:

代码:

[html]view plaincopy 
   
 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Demo.aspx.cs" Inherits="WebApplication1.Demo" %>  
   
 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  
   
 <html xmlns="http://www.w3.org/1999/xhtml">  
 <head runat="server">  
     <title>Tim Demo 演示</title>  
 </head>  
 <body>  
     <form id="form1" runat="server">  
     <div>  
         <asp:GridView ID="GridView1" runat="server"   
             onrowdatabound="GridView1_RowDataBound">  
         </asp:GridView>  
     </div>  
     </form>  
 </body>  
 </html>  

后台:
