I have a Development and Production environment both attempting to run the RadEditor Lite version. In Development everything works as expected. In production when I attempt to edit a page I get te following error
05/15/2008 18:56:14.90 w3wp.exe (0x1554) 0x06B8 Windows SharePoint Services General 8nca Verbose Application error when access /schools/test0001/Pages/default.aspx, Error=The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). at System.Web.UI.ControlCollection.Add(Control child) at Telerik.RadEditorUtils.RadControl.RegisterCssFile(String path) at Telerik.RadEditorUtils.RadControl.RenderRuntimeSkin() at Telerik.RadEditorUtils.RadControl.Page_PreRenderComplete(Object sender, EventArgs e) at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Web.UI.Page.OnPreRenderComplete(EventArgs e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
The layout page and web.config files are identical on both sites. any help is appreciated.
I have found several posts that state that you cannot have <%%> in the <head> tag. The question is why does it work sometimes and not work others. I do have <%%> in the <head> but I cannot get rid of them.
Thanks,
Bill

Hi Bill,
Indeed, this problem is observed when there is a script block in the HEAD tag. To solve the problem, you should remove the script block from the head tags and put it somewhere else (e.g. put it in the body). Also please check the head for runat="server" attribute and if it is present please remove it.
The following Google search lists a lot of forum discussions on this topic on various ASP.NET community sites:

I hope this helps.

Hello George,
Thank you for the feedback, but unfortunately I cannot remove either the "runat" or the <%%> from the head. I have information that needs to be populated there. The real question is why does this only fail some of the time? Meaning, why does this problem not manifest itself in my development box, but only seems to be happening on production. Is there a fix coming for this? Have you identified to code that fails? Is it yours or is it SharePoint itself?
Thanks again,
Bill Safcik

I'm getting the same error and nothing I've read here seems to work. I've removed all code blocks from the head and put them into a RadCodeBlock within the page but I still get this error. If I replace the RadAjaxPanels with UpdatePanels I don't get the error. I'm not sure what else to try, but my project is due in a couple days and I can't get pages to load with Telerik controls on them! This should only happen if there is asp.net code blocks in the head, right? Of course I do have Javascript and CSS references in the head of my master page, but they are referenced directly, not using any asp.net code blocks. That can't be causing this, can it?
Do you have any other suggestions?

Hi Eddie,
Could you please open a support ticket and send me the problematic ASPX page. I will check it and do my best to provide a solution.
Note that, the RadCodeBlock should be used when you have server code blocks placed within the markup (most often some JavaScript functions accessing server controls) and it prevents the server error:
System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
For example:

Hello Frank,
If the code that you need to run is in the head tag, you should make sure that there is no runat="server" attribute in it.
I hope this helps.

Probably a late reply but placing the .net code between de telerik code blocks works fine for me. The .net error doesn't show up any more. In my example I use a randomizer which doesn't work when the radcodeblocks are not placed.
Even when the "Head" has the attribute runat="server", I have no problems.
Example, just placed this in my PageLayout.
Works fine!

height: 237px;
width: 948px;
