Routing issues in asp.net MVC 4

Question

I am a beginner in MVC 4. I have an url ../Home/NameDetailsPage/20 where controller= Home, action=NameDetailsPage and pageIndex= 20. How do i write my route engine for this url?

routes.MapRoute(
 ......
 .....
);

In controller, NameDetailsPage works pretty fine for default page such as int page=2 :-

 public ActionResult NameDetailsPage(int? page)
    {

        var context = new BlogContext();
        IQueryable<string> list;
        list = from m in context.Blogs.OrderBy(m => m.BlogId)
               select m.Name;

        ViewBag.total = list.ToArray().Length;
        ViewBag.page = page;

        var pageNumber = page ?? 1;
        ViewBag.page1 = pageNumber;

        return View("NameDetails", list.Skip(pageNumber * 4).Take(4));
    }

But the pageNumber is always 1 whatever pageIndex in the url. So It shows same result for all the pageIndex. How can I set pageNumber other than 1. Thanks in Advance.

What routing have you tried? What did you see that was different to what you expected? — Ant P

routes.MapRoute( name: "Page", url: "Home/NameDetailsPage/{id}", defaults: new { controller = "Home", action = "NameDetailsPage", id = UrlParameter.Optional } ); — sharif2008

When you have a route like the following

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

The defaults object properties (controller, action, id) are what can be passed to the action (if the action has parameters that match the name).

So if you have an action:

public ActionResult NameDetailsPage(int? page)

there are no values being passed from the URL as page.

You can either change {id} to {page}, or preferably:

public ActionResult NameDetailsPage(int? id)

Based on your comment you are most of the way there. You just need to define the parameter you are passing to the action. In this case switching {id} for {page} and altering the defaults to suit.

routes.MapRoute( 
    name: "Page", 
    url: "Home/NameDetailsPage/{page}", 
    defaults: new { controller = "Home", action = "NameDetailsPage", page = UrlParameter.Optional } );
