UpdatePanel 让我发疯 - 动态创建的 UpdatePanel 问题

因此，我在 Page_Load 中有以下代码：

updDesignations = new UpdatePanel();
updDesignations.ContentTemplateContainer.Controls.Add(toutLineDesignation);            
updDesignations.ChildrenAsTriggers = true;
updDesignations.UpdateMode = UpdatePanelUpdateMode.Always;            
divDesignations.Controls.AddAt(0,updDesignations);

当我单击此动态创建的更新面板中的链接按钮时，将在服务器上调用适当的事件处理程序。但是，所做的任何更改都不会保留回客户端，并且来自更新面板 AJAX 调用的 HTTP 响应始终为空：

请求格式正确，并且包含正确的表单提交信息，响应很简单：

Server  Microsoft-IIS/5.1
Date    Tue, 07 Apr 2009 22:30:57 GMT
X-Powered-By    ASP.NET
X-AspNet-Version    2.0.50727
Cache-Control   no-cache, no-store
Pragma  no-cache
Expires  -1
Content-Length  0

This is moving我疯了，因为这必须是动态创建的更新面板。我究竟做错了什么？

So, I have the following code in Page_Load:

updDesignations = new UpdatePanel();
updDesignations.ContentTemplateContainer.Controls.Add(toutLineDesignation);            
updDesignations.ChildrenAsTriggers = true;
updDesignations.UpdateMode = UpdatePanelUpdateMode.Always;            
divDesignations.Controls.AddAt(0,updDesignations);

When I click on a Linkbutton within this dynamically created update panel, the appropriate event handler is called on the server. However, any changes made are not persisted back to the client, and the HTTP response from the update panel AJAX call is always empty:

The request is properly formed, and includes the correct form submission information, the response is simply this:

Server  Microsoft-IIS/5.1
Date    Tue, 07 Apr 2009 22:30:57 GMT
X-Powered-By    ASP.NET
X-AspNet-Version    2.0.50727
Cache-Control   no-cache, no-store
Pragma  no-cache
Expires  -1
Content-Length  0

This is driving me nuts, as this has to be a dynamicly created update panel. What am I doing wrong?
