Controllers in subfolders ASP.Net MVC 4

Question

In my ASP.Net MVC 4 project, I have a controllers in a sub-folder in controller folder-

/Controllers
    /GroupA
        /AbcController.cs

In AbcController, i have two methods-

    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Edit(string value)
    {
        ViewBag.Message = value;
        return View();
    }

RouteConfig.cs -

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "TestRoute",
            url: "GroupA/{controller}/{action}/{id}",
            defaults: new { controller = "AbcController", action = "Index", id = UrlParameter.Optional }               
        );

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }

but when i browse http://localhost:2240/groupa/abc/edit/somevalue

, 'somevalue' is not passed to the method. It shows null.

What i am missing here?

if I recall correctly, isn't it solved by either .../groupa/abc/edit?somevalue as url or changing public ActionResult Edit(string value) to public ActionResult Edit(string id) i.e. you name your parameter id in the route, but value in the method — Major Byte

MVC Areas will give you another hierarchical level for your routes ("subfolders"). — Jasen

@Jasen, Yes MVC Area is the way to go. Before I also used the way OP is doing, but only recently I learnt about Areas and it is very easy to use. — Dush

In your route, your parameter is declared as id while in your action method it's declared as value. Pick one and stick to it.

routes.MapRoute(
    name: "TestRoute",
    url: "GroupA/{controller}/{action}/{value}",
    defaults: new { controller = "AbcController", action = "Index", value = UrlParameter.Optional }               
);

public ActionResult Edit(string value)
{
    ViewBag.Message = value;
    return View();
}

Edit : while we're on the subject, I recommend you give AttributeRouting a look.
