使Div内内容可编辑

呵呵，仅IE有效：）
前台代码：

<% @ Page Language = " C# "  AutoEventWireup = " true "   CodeFile = " Default.aspx.cs "  Inherits = " _Default "   %>

<! 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 > 无标题页 </ title >
</ head >
< body >
     < form  id ="form1"  runat ="server" >
     < div  style ="width:600px;height:400px;"  id ="div1" >
         < asp:GridView  ID ="GridView1"  runat ="server"  Height ="300px"  Width ="200px" >
         </ asp:GridView >
         &nbsp; </ div >
     < script  language ="javascript"  type ="text/javascript" >
       document.getElementById( " div1 " ).contentEditable  =   true ;
       document.execCommand('2D - Position',  true ,  true ); 
     </ script >
     </ form >
</ body >
</ html >
