为什么我的datagird的编辑更新取消不可用？

我在新页面画了一个label来接收。我写得对吗？怎么接受的内容都是{0}呢? a.aspx
<asp:HyperLinkColumn DataTextField="title" HeaderText="主题名字" NavigateUrl="text.aspx?title={0}"></asp:HyperLinkColumn>
text.aspxLabel1.Text=Request.QueryString["title"];我是新手.见笑了!

{0}就是代表 DataTextField="title",title字段的内容.还有你的编辑，更新，取消事件没有加，所以你不能实些你需的功能<asp:DataGrid id="DataGrid1" OnCancelCommand="btnCancel" ……>然后在相应该的事件里写code，你可以参照msdn

后面的我去查阅msdn多谢。可是我怎么点击了他显示的内容就是{0}而不是具体数值呢?我菜的要命请见谅了!

还是不行。我听说他们是代码分离什么的。不能把这个写到code里面去吗？辛苦您啦。就是最后解决不了我还是给您分！

HTML我帮你改了一下，你试试

然后你再使用Request来接收，试试吧，应该可以了
