Asp.net mvc routing : ActionLink return an url with parameters in querystring

Question

I try to have an URL like this /Forum/Index/2

for url I have a route {controller}/{action}/{page} in my global.asax

If I test the above URL with the Route Debugger it corresponds to the above route ( and some other but this is the first one in the list )

but if I create an url with the ActionLink ( like this : <%= Html.ActionLink(item.Title, "Index", new { controller = "Forum", page = page })%> ), this methode return me this URL /Forum/Index?page=2

Is there a way to have an URL with nothing in querystring with the ActionLink method?

This are all my routes and the match route is named DefaultWithPager :

Answer 1

The way Mvc routing works is that it evaluates each of the routes in order and will use the first one that matches. In your case the first one to match will be the:

routes.MapRoute(
    "Default",
    "{controller}/{action}",
    new { controller = "Home", action = "Index" }
);

As that route doesn't have any mappings for page it will append it on to the url as get parameters.

If you want it to hit the one with the page mapping that should come before any other routes that will match the route data you're passing in.

It should always go from most to least specific.

Answer 2

It sounds like your route registration is just fine. You just need to use the Html.RouteLink helper and tell it the name of the route to use:

<%= Html.RouteLink(item.Title, "DefaultWithPager", new { controller = "Forum", page = page })%>
