------解决方案--------------------
例子，上面的，遍历控件取得<a>标签，判断权限，链接写到后台，给提示，就好了
要结贴，呵呵

------解决方案--------------------
<ItemTemplate> 
  <div id="test">
 <a target="_blank" href="">查看邮件</a>&nbsp;
</div>
  <a href="" target="_blank" runat="server">回复</a>
</ItemTemplate>
然后控制div的display:none  、 block

------解决方案--------------------
用三元运算符?:

<asp:TemplateField HeaderText="操作">
<ItemTemplate> 
<%#Eval("CanDoSomething").ToString()=="1"?"可以查看的HTML":""%>
</ItemTemplate>
</asp:TemplateField>
