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！
