Answer 2

UpdatePanel不能嵌套在table
---------
可以,一定可以.估计是你有语法错误.我一直都是把UpdatePanel嵌套在table中的.楼主可以把签到工作放到设计界面去做而要放在源去做,这样就不会出现语法错误了.这与你这个,UpdatePanel应该放在table的td中.
我写个简单点的.
<table>
 <tr>
  <td>
   <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <table>
    ,,
    </table>
   </asp:UpdatePanel>
  </td>
 </tr>
</table>这样套就没问题了.

Answer 3

不需要 <ContentTemplate>吗

Answer 4

晕，好像2楼是对的，你把更新控件嵌套到表格中，楼主你放错位置了，表格只有（td）也就是单元格中才可以放其他控件的，你放在table下面肯定是不行的撒

Answer 5

<table>
<tr>
  <td>只有这中间才可以加入新的东西或者别的什么控件</td>
</tr>
</table>table和tr之间是不能加其他的东西的，只有单元格里面才可以加

Answer 6

lz那样放什么控件都不行，只有放在td中，在TD中放其他控件
