This question already has answers here: ASP.NET MVC Relative Paths (9 answers) Closed 2 years ago.

context: I am currently developing my first MVC application, I am following the examples in the book "Pro ASP.NET MVC Framework 2" by Steven Sanderson. I followed the first chapters and I have implemented a similar application to the "SportStore" full code can be located at the following link http://pastie.org/2451370

The application has two controllers

1 .- NavController designed to implement a user menu using a user control "Menu.ascx"

2 .- PostEntryController designed to list the post belonging to a particular menu option

The problem arises when running the application in debug mode NavController generated links do not work for some reason the PostEntryController is not instantiated.

When I examine the source code generated aspx file is shown as (PostEntry/Index.aspx)

<li><span class="folder"><a href="/PostEntry/Index/4/1">Browser</a></span></li>
</ul>
</div>
</html>

Can anyone help me?

This is Global.asax

routes.MapRoute("PostEntry", "PostEntry/{action}/{MenuItemId}/{page}", // Matches ~/MenuId
            new { controller = "PostEntry", action = "Index", MenuItemId = (string)null },
            new { page = @"\d+" }
        );

        routes.MapRoute("MenuItem", "PostEntry/{action}/{MenuItemId}", // Matches ~/MenuId
            new { controller = "PostEntry", action = "Index", MenuItemId = (string)null, page = 1 }
        );

        routes.MapRoute(null, "", // Only matches the empty URL (i.e. ~/) 
            new { controller = "PostEntry", action = "Index", MenuItemId ="0", page = 1}
        );

When I write the url in the address bar I can access the url

According to your description, I believe the link generation went wrong. So look at html source from the browser and see if the links are correctly generated.
