Sitecore 7.0 and a Sublayout with a RadEditor - Web.Config Registeration missing!

[Ruben]

Hey guys, I'm stuck with this issue. I basically added a couple of radeditors under a sublayout for some page at my sitecore CMS, and when I go to the page everything looks fine with the RadEditor till I try to add a link, image, etc. I've been reading a lot about this without luck. I also checked this article: http://www.telerik.com/support/kb/aspnet-ajax/editor/details/error-web-config-registration-missing!-the-telerik-dialogs-require-a-httphandler-registration-in-the-web-config-file- 

My web.config looks fine, with all the handlers in place and so. So now just wondering whether this is an issue with the sitecore configuration or something?

My web.config looks like this:

    <handlers>
      <add name="Telerik_Web_UI_DialogHandler_aspx" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" />
      <add name="Telerik_Web_UI_SpellCheckHandler_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" />
      <add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />
    </handlers>

    </httpHandlers>
      <add verb="*" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" />
      <add verb="*" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" />
      <add verb="*" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />
    </httpHandlers>

Hi Ruben,

We do not support the Sitecore platform as we cannot know what additions and modifications they make.

The described issues seems like some URL rewrites or other modifications in the CMS that break our handler. I can, therefore, advise that you contact their support team for assistance with this integration, because a sample application on my end works fine (I took the handlers from this page: http://www.telerik.com/help/aspnet-ajax/web-config-settings-overview.html#mandatory-additions).

You can begin with monitoring the network requests to see what is the error you receive when the handler is called, because this may be a simple permissions issue and you may only need to allow access to the needed handlers: http://www.telerik.com/help/aspnet-ajax/introduction-troubleshooting.html#radscriptmanager-login-page-error.
