Additional MVC Route with Optional Parameter

Question

I want to add a custom route, but I can't get it to work. I want to use normal routing, except when it hits a specific controller,to use a different optional parameter instead of id.

In my area, this exists:

context.MapRoute(
     "Admin_default",
     "Admin/{controller}/{action}/{id}",
     new { action = "Index", id = UrlParameter.Optional }
     );

and above that I tried to add:

context.MapRoute(
           "Admin_Users",
           "Admin/Users/{action}/{username}",
           new { action = "Index", username = UrlParameter.Optional }
       );

And in code, I call the page with:

@Html.ActionLink("Edit", "Edit", new { username=user.UserName })

and it works, but the link shows up as /Admin/Users/Edit/?username

and I want: /Admin/Users/Edit/username

However, I want to keep the same route for all my other pages, that being:

/Admin/Shop/Products/Edit/1

which uses the default routing

EDIT

I got it to work by adding in controller="Users", in my route.

context.MapRoute(
       "Admin_Users",
       "Admin/Users/{action}/{username}",
       new { controller="Users", action = "Index", username = UrlParameter.Optional }
   );

I thought this was the point of the URL part (the line above) of it?

Please, stop referring to "ASP.NET MVC" simply as "MVC". One is a framework, while other is a language-independent design pattern. It's like calling IE - "the internet" — tereško

your code is correct, but your order is not.

ASP.NET MVC uses the first route that applies. In your case, the generic route will apply. Change the order and your 'Admin/User/...' route will have higher precedence.

I think that's the problem. It didn't work above or below, but I think it's because the default route works for everything under Admin/Users also.
