    I'm currently attempting to use the RadEditor in a mixed project that contains routing for MVC, WebAPI, and Friendly URLs.  I'm getting errors when I attempt to open the ImageManager dialog box from within the Editor.  I suspect this has something to do with the routing rules, but all my attempts to exclude the dialogs has failed so far.  

    The dialogs are registered in web.config (both, system.webserver and system.web).

    Does anyone have the specifics on what to add to the routing config?  Or if you've encountered this, and it isn't the routing, please shed some light!

    Thank you in advance,

    Hello Alex,

    You can read more about the described topic here: 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-. Basically, as axd handlers are not being redirected, at least, I suppose so, you can switch to using the DialogHandler.axd instead of the aspx one. Which is the last suggestion in the KB from this link.

    You should note, however, that UI for ASP.NET AJAX is not supported in an MVC environment. This is mentioned in this article: http://docs.telerik.com/devtools/aspnet-ajax/mvc/overview
