Hi there,
I am using telerik RadEditor like this in asp.net web application.
ASPX
ASPX.CS
Had set Image Paths from server side.
WEB.CONFIG
TELERIK ASSEMBLY VERSION : Version=2010.2.713.20
Giving me exception as Using themed css files requires a header control on the page. (e.g. <head runat="server" />). when clicked on Image Manager on editor. With web.config error message as
Web.config registration missing!
The Telerik dialogs require a HttpHandler registration in the web.config file. Please, use the control's Smart Tag to add the handler automatically, or see the help for more information: Controls > RadEditor > Dialogs > Introduction
Kindly help me to resolve the issue.
Regards,
Swapnil

Hi,
For your convenience, I pasted below the solution that one of our customers proposed for the reported error:

For your convenience, I pasted below the solution that one of our customers proposed for the reported error:
We are compiling our .net web site project to a dll. When we compile the web site, it writes the current theme to each page's head for some reason. To override this I had to write a piece of code on Application_PreRequestHandlerExecute which gets the current page and sets the theme we specified in web.config. Everything works just fine, but when I added the rad spell, which opens a dialog I get the following error:
After looking into it a bit more underlying error which causes that is:
Using themed css files requires a header control on the page. (e.g. <head runat="server" />).
I don't have the full source code version of radcontrols for .net, so I can't change the handler's head to have the runat="server". I solved the problem by adding a check where I set the theme to check that if the page is a dialog handler or any other telerik handler, I won't force the theme. Of course if you would add that runat to the head, then everything would be solved.
Example code:

Hi Rumen,
Thanks for the reply.
I tried above code in Global.asax file still it doesn't solve my problem.
Its still giving me the same error "Using themed css files requires a header control on the page. (e.g. <head runat="server" />). ".
