所以我最近一直在试图查看我一直在通过iis7工作的网站时获得这个httpexeption。下面的错误是：如何正确处理/调试HttpExceptions？
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

在做对这个问题的研究，唯一可行的解决方案，我有似乎发现了包裹的javascript radcodeblock内或使用<span runat="server">。我已经尝试了这两种方法，似乎都没有工作。我也有点困惑，为什么我会得到这个错误，因为没有任何由本网站以前的开发人员实施的JavaScript包含任何项目，据我所知，使用<%...%>。
此外，我已经提前检查并检查了页面中的所有控件，以确保其抱怨的上述情况实际上并未发生。换句话说，据我所知，在代码中没有任何地方使用<%...%>，而不是在页面的声明中。即：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="LoginPage.aspx.cs" Inherits="Datamart.UI.Reporting.Web.LoginPage" culture="auto" meta:resourcekey="PageResource1" uiculture="auto" ValidateRequest="False" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
所以我想知道它是什么我可能是做错了还是什么将是找出哪里和我的究竟是什么问题的下一个步骤。当我认为是存在的位于下面的错误：
<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
<script type="text/javascript">
function onTabSelecting(sender, args)
{
if (args.get_tab().get_pageView())
{
if (args.get_tab().get_pageView().get_id())
{
args.get_tab().set_postBack(false);
}
}
}
function StopPropagation(e)
{
//cancel bubbling
e.cancelBubble = true;
if (e.stopPropagation)
e.stopPropagation();
}
//the following code use radconfirm to mimic the blocking of the execution thread.
//The approach has the following limitations:
//1. It works inly for elements that have *click* method, e.g. links and buttons
//2. It cannot be used in if(!confirm) checks
window.blockConfirm = function(text, mozEvent, oWidth, oHeight, callerObj1, oTitle)
{
var ev = mozEvent ? mozEvent : window.event; //Moz support requires passing the event argument manually
//Cancel the event
ev.cancelBubble = true;
ev.returnValue = false;
if (ev.stopPropagation)
ev.stopPropagation();
if (ev.preventDefault)
ev.preventDefault();
//Determine who is the caller
var callerObj = ev.srcElement ? ev.srcElement : ev.target;
//Call the original radconfirm and pass it all necessary parameters
if (callerObj)
{
//Show the confirm, then when it is closing, if returned value was true, automatically call the caller's click method again.
var callBackFn = function(arg)
{
if (arg)
{
callerObj["onclick"] = "";
if (callerObj.click) callerObj.click(); //Works fine every time in IE, but does not work for links in Moz
else if (callerObj.tagName == "A") //We assume it is a link button!
{
try
{
eval(callerObj.href)
}
catch (e) { }
}
}
}
radconfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);
}
return false;
}
function noBack()
{
window.history.forward();
}
noBack();
window.onload = noBack;
window.onpageshow = function(evt)
{
if (evt.persisted) noBack();
}
window.onunload = function()
{
void (0);
}
</script>
</telerik:RadScriptBlock>
这在我的页面的正文中，但我已经尝试过移动到页面的底部，以及在头部，因为被发现成为其他人可能的解决方案，但无济于事。
任何帮助或建议，非常感谢。谢谢。
