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！
