                                   </ContentTemplate>
                               </asp:UpdatePanel>
                           </td>

推荐答案

设置ScriptManager.EnablePartialRendering = true

Set ScriptManager.EnablePartialRendering =true

我发现它是我自己的。 Ispostback = true



谢谢大家

I found it my self. Ispostback=true

Thanks Everyone
