GridView多行编辑，取不到值！

悬赏园豆：100 [已关闭问题]

有个需求就是同时支持GRIDVIEW里面的所有行同时编辑，最后在页面下方点击“保存”来遍历保存GRIDVIEW上的所有项。     为了使GRIDVIEW能够同时支持编辑，我在GridView1_RowDataBound 事件里写入了以下处理： <DIV class=cnblogs_code><IMG src="http://space.cnblogs.com/Images/OutliningIndicators/None.gif" align=top>    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) <IMG id=Codehighlighter1_85_590_Open_Image onclick="this.style.display='none'; document.getElementById('Codehighlighter1_85_590_Open_Text').style.display='none'; document.getElementById('Codehighlighter1_85_590_Closed_Image').style.display='inline'; document.getElementById('Codehighlighter1_85_590_Closed_Text').style.display='inline';" src="http://space.cnblogs.com/Images/OutliningIndicators/ExpandedBlockStart.gif" align=top><IMG id=Codehighlighter1_85_590_Closed_Image style="DISPLAY: none" onclick="this.style.display='none';

tb.Text = e.Row.Cells[i].Text == " " ? "" : e.Row.Cells[i].Text; 这样好像无论如何取道的值都是不会变的吧 http://files.cnblogs.com/clhed/downComicWeb.rar 这儿有个例子（例子更新过了）换个数据源就可以用这里有个全选可以改变gridview里的选定项目

我想问楼主想要实现什么功能，如果想用TextBox框，我觉得可以转为模板列，
