C# 刷新模式弹出窗口内的UpdatePanel

显然我做错了什么，只是不确定。。。 我有一个模式弹出窗口，里面是一个更新面板，其中依次包含一个gridview。当第一次调用模式弹出窗口时，我想刷新UpdatePanel（和网格数据）

我有工作的代码，以便面板更新时，按下按钮BTNHIDENJSREFRESH（目前未隐藏）。但是我不能不按按钮就让它工作

我已尝试通过Jquery$（“”）单击按钮； 我可以看到它被调用了，但是页面上没有反应。 与“doPostBack”（“，”）相同

此外（这可能是不相关的）gridview中的delete选项在这里不起作用。在UpdatePanel之外，它工作正常

这是代码，我已经试着把它减少到主要的问题领域

<ajaxact:modalpopupextender id="ModalPopupExtender1" runat="server"
cancelcontrolid="ClosePopup" okcontrolid="ClosePopup"
targetcontrolid="hidenSelectedDoc" popupcontrolid="THolder"
popupdraghandlecontrolid="PopupHeader" drag="true" BehaviorID="MPE" Y="0" backgroundcssclass="ModalPopupBG">

任何想法都很好

谢谢

在代码片段中引用所有页面代码会更有帮助。同时，我试图根据您的描述模拟此功能，因此如果我误解了什么，请纠正我

在页面加载中，我添加了一个javascript块来检查它是否是回发。如果不是，那么我调用按钮的（btnHiddenJSRefresh）单击事件一次以重新显示模式。另外，我添加了一个按钮来弹出模式窗口，请参见我的代码示例。最后，在本例中，delete选项工作正常
