Question

Hi im having a problem to figure this out, i am literally going nuts. I got a scenario like this. Category , Category-SubCategory, Category-SubCategory-SubSubCategory

I cant for the life of me figure out this route. My last and current is like this

routes.MapRoute(
            "Navigation", 
            "Navigation/{nav}/{sub}/{subsub}/{id}", 
            new { controller = "Navigation", action = "Site", nav = UrlParameter.Optional, sub = UrlParameter.Optional, subsub = UrlParameter.Optional, id = UrlParameter.Optional }
        );

I figure like this that UrlParameter.Optional would skip the sub or the subsub but instead it puts system.UrlParameter.Optional as a parameter there. Any ideas on how this can be handled?

EDIT 1:
so far i limited the site with 2 sub categories and did 3 routes and 3 actionresults. not a pretty solution but works for now

Answer 1

Cut it to one route by cheating a bit.

routes.MapRoute(
            "navigation",
            "{nav}/{name}",
            new { controller = "Navigation", action = "Page", nav = UrlParameter.Optional, name = UrlParameter.Optional }
        );

and i write all the categories, subcategories in the nav like

<%: Html.ActionLink("HOME", "Page", "Navigation", new { nav = "Category/Sub/", name = "Name" }, null)%>

i figure the {nav} dont really got any function here except to show the category path and in case i need to break it out ill use the string spliter.
