TinyMCE Spellchecker in ASP .NET MVC

Question

I followed the tutorial described here, in order to make the TinyMCE Spellchecker work on a Webforms application. But I tried to do the very same thing on a MVC project and keep getting errors every time I try to use the spellchecker. I'd like to know what changes or adjustments I need to make in order to make this word on an ASP .NET MVC project. The error I'm getting is the following: ``` [HttpException]: The controller for path '/TinyMCE.ashx' could not be found or it does not implement IController. at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(Type controllerType) at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContextBase httpContext) at System.Web.Mvc.MvcHandler.ProcessRequest(HttpContext httpContext) at System.Web.Mvc.MvcHandler.System.Web.IHttpHandler.ProcessRequest(HttpContext httpContext) at System.Web.HttpApplication.CallHandlerExecutionStep.S…

Accepted Answer

Well its a bit hard to know what the problem is without knowing what the error you're getting is, but I'm guessing that its because you need to ignore the route to the spell checker in your MVC. Do this by adding something like this to your MVC route definitions:

```
//ignore just the TinyMCE spell checker service:
routes.IgnoreRoute("TinyMCE.ashx");
//or if you want to be more general & ignore all ashx's:
routes.IgnoreRoute("{resource}.ashx{*pathInfo}");
```

Without the above it would be interpreting the spellcheck request url (`TinyMCE.ashx...`) as an MVC route & try to find a matching Controller (& obviously fail).

If that's not the issue, I'd suggest posting some more info about the specific error you're seeing.
