Question

I’d like to map a new route after I commit a new object to db. So for example if i enter object with name “Test” I would like to have a new route immediately, to resolve “Test.aspx“.

I tried

System.Web.Routing.RouteTable.Routes.MapRoute(obj.NameUrl, obj.NameUrl + extension, new { controller = "per", action = "Index", name = obj.NameUrl });

in controller but it does not work (no error, just probably not right time in life cycle?). Same code works in Application_Start()

You should avoid registering routes dynamically. The following static route in your Application_Start should be able to handle your scenario of having dynamic route parameters:

routes.MapRoute(
    "page",
    "{name}.aspx",
    new { controller = "per", action = "index" },
    new { name = @"[a-z0-9]+" }
);

and if the extension has to be dynamic as well:

routes.MapRoute(
    "page",
    "{name}.{extension}",
    new { controller = "per", action = "index" },
    new { name = @"[a-z0-9]+", extension = @"[a-z]{3,4}" }
);

and then you could have the Index action to handle requests to this route:

public class PerController: Controller
{
    public ActionResult Index(string name, string extension) 
    {
        ...    
    }
}

and if you want to generate a link to this action:

@Html.RouteLink("go to foo", "page", new { name = "foo", extension = "aspx" })
