同一页面放置多个UpdatePanel

ScriptManager添加EnablePartialRending属性：

        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true">         </asp:ScriptManager>

所有的UpdatePanel需要设置UpdateMode="Conditional"：

 <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">                                                 <ContentTemplate>                                                                                                    </ContentTemplate>                                                 <Triggers>                                                     <asp:AsyncPostBackTrigger ControlID="" EventName="Click" />                                                 </Triggers>                                             </asp:UpdatePanel>

其他操作是一样，这样，在同一个页面上的多个UpdatePanel可以独自刷新，不会互相影响了！
