Question

I have a simple action:

    public ActionResult CommentError(string error)
    {
        return View(error);
    }

I have a simple partial view called CommentError.ascx:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<String>" %>

<%: Model %>

When I browse to the view directy by going to myurl.com/find/Comments/CommentError the view displays fine… no errors.

But, when I go to myurl.com/find/Comments/CommentError?error=SomeErrorString, instead of binding the querystring to string error, it looks for a view called SomeErrorString.ascx.

Why is this happening?

Edit
Note, i do have a custom global.asax as indicated by the paths I’m using (/find/Comments/CommentError ::: /find/{controler}/{action})

As mentioned, MVC is looking for a view named the same as the string parameter. To avoid this, you need to cast it to an object…

public ActionResult CommentError(string error)
{
    return View((object)error);
}
