[英]AJAX SciptManager causing problems
I'm trying to get a ScriptManager working in .NET 3.5 but getting a scriptmanager exception. 我试图让一个ScriptManager在.NET 3.5中工作,但是获得了一个scriptmanager例外。 I've just removed all of the UpdatePanels from the page and refactored everything into UserControls so the page is no longer written like a VB5 app. 我刚从页面中删除了所有UpdatePanel,并将所有内容重构为UserControls,因此页面不再像VB5应用程序那样编写。 The ToolkitScriptManager is on the masterpage, and I've tried with and without a ScriptManagerProxy on the offending page. ToolkitScriptManager位于主页面上,我在有问题的页面上尝试使用和不使用ScriptManagerProxy。
I get a stacktrace with the following error: 我得到一个堆栈跟踪,出现以下错误:
The Controls collection cannot be modified because the control contains code blocks (ie <% ... %>).
Stack Trace: 堆栈跟踪:
[HttpException (0x80004005): The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).]

I can't see any <%= tags in the code and I'm getting desperate now. 我在代码中看不到任何<%=标签,现在我变得绝望了。 How would I go about tracing the source of the error. 我将如何跟踪错误的来源。 Any help is appreciated. 任何帮助表示赞赏。
除了删除和<%= ..%>
,请确保您没有Response.Write
。在代码隐藏中写入任何内容。
