MVC3 Routes with areas... a little confusion - c#

I have an MVC3 site with 2 areas plus the common area. I also have a route specified for paginating lists of items. My Register_Routes method looks like so:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Paginate", // Route name
"{controller}/Paginate/{itemsPerPage}/{pageNumber}/{searchString}", // URL with parameters
new { controller = "Home", action = "Index", itemsPerPage = SiteSettings.ItemsPerPage, pageNumber = 1, searchString = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
What I've noticed (and don't understand) is if I log out from my home page, the redirect from my login page looks like
http://localhost:62695/Account/LogOn?ReturnUrl=%2fHome%2fPaginate
... and upon logging in, I end up on my home page, except with a URL of:
http://localhost:62695/Home/Paginate
I'm fairly certain at this point that I've screwed something up with the route map, but it seems right to me. What am I doing wrong?
UPDATE
per suggestion, I changed my routes to look like this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Paginate", // Route name
"{controller}/Paginate/{itemsPerPage}/{pageNumber}/{searchString}", // URL with parameters
new { controller = "Home", action = "Index", searchString = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
... and the home index pages do indeed seem to work properly, but now the paginates don't:
return RedirectToAction("Paginate", new { itemsPerPage = SiteSettings.ItemsPerPage, pageNumber = 1, searchString = string.Empty });
in a Admin\HomeController yields the URL:
http://localhost:62695/Admin/Users/Paginate?itemsPerPage=25&pageNumber=1
so I'm still doing something wrong here.
UPDATE 2
OK, this is how I got it to work the way I wanted it to:
My RegisterRoutes method now looks like this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
null,
"{area}/{controller}/Paginate/{itemsPerPage}/{pageNumber}/{searchString}", // URL with parameters
new {area = string.Empty, controller = "Home", action="Paginate", searchString = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{area}/{controller}/{action}/{id}", // URL with parameters
new {area = string.Empty, controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
... but this was not enough to fix the routing issues. Additionally to this, I needed to add the route to my area registrations. My AdminAreaRegistration looks like this:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
null,
"Admin/{controller}/Paginate/{itemsPerPage}/{pageNumber}/{searchString}", // URL with parameters
new { controller = "Home", action = "Paginate", searchString = UrlParameter.Optional } // Parameter defaults
);
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
This, in addition to changing to RedirectToRoute for my connections, made my URLs all pretty and working at the same time. All the answers helped to get to my goal, I +1'd everyone and chose the answer that got me closest to the path.

Routes are evaluated in the order they are registered. The redirects are being generated by the first route that you registered, especially since you declared default values for all of the segments. You might want to consider defining a more specific route
UPDATE
Use RedirectToRoute instead of RedirectToAction to get your desired URL generation
RedirectToRoute("Paginate", new { itemsPerPage = SiteSettings.ItemsPerPage, pageNumber = 1, searchString = string.Empty });

routes.MapRoute(null, // do not name your routes, it's a "magic string"
"{controller}/Paginate/{itemsPerPage}/{pageNumber}/{searchString}",
new
{
controller = "Home",
action = "Index",
searchString = UrlParameter.Optional
}
);
// instead of RedirectToAction, try RedirectToRoute, and do not use the route name
return RedirectToRoute(new
{
controller = "Home",
area = "AreaName",
itemsPerPage = SiteSettings.ItemsPerPage,
pageNumber = 1,
searchString = string.Empty,
}
);

Well, the reason you return to the URL http://localhost:62695/Home/Paginate is because when you log in you return to the URL specified, namely the ?ReturnUrl=%2fHome%2fPaginate part of http://localhost:62695/Account/LogOn?ReturnUrl=%2fHome%2fPaginate. Is that not the URL of your home page? You never specified.
It could be that the first definition takes precedence also, not sure where I heard that, so maybe if you put the default definition first it will grab that.

Routing config issue cannot be resolved

Given this URL's
http://localhost:51095/Person // This is equivalent to this one Person/Index
http://localhost:51095/Person/Allan
I setup a route config for it as follows :
routes.MapRoute(
"Person",
"Person/{personName}",
new { controller = "Person", action = "Person", personName = UrlParameter.Optional }
)
;
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
First URL should follow the Default route and the second should follow the Person route.
This is not working because the first config seems to catch all these URL's
The first thing I'd do is remove personName = UrlParameter.Optional in the first Route. This would allow only urls that provide a personName value to access this Route. If no value is provided, it should fall through to the default Route.
But you'd want to think about the future with this strategy: if you implement new actions on that Person controller, you'd need to add a new Route for each of them. If you had a new 'Edit' action for example:
routes.MapRoute(
"Person_Edit",
"Person/Edit/{personName}",
new { controller = "Person", action = "Edit" }
)
You'd want to add these new Routes before the first one though - ordering/precedence of Routes is important.

MVC Routing Parameter Not Being Passed

I am trying to do some MVC routing, following online tutorials, but for some reason the routing is not working.
I am trying to do http://www.website.com/news/news-title
The route I am trying to do is below.
routes.MapRoute(
"News",
"{controller}/{url}",
new { controller = "News", action = "Index", url = "" }
);
Within my NewsController I have the following ActionResult.
public ActionResult Index(String url)
{
return View();
}
However, when stepping thorough the code, url is not being populated.
Thanks
== Update ==
Thank you all for your replies.
I have no amended the Route to below
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.LowercaseUrls = true;
routes.Add(new SubdomainRoute());
routes.MapRoute(
"News",
"News/{action}/{slug}",
new { controller = "News", action = "Index" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
This URL works: /news/index/?slug=test-news-title
But this URL does not: /news/index/test-news-title
=== Further Edit ===
It appears my subdomain route is messing with it. If i remove the subdomain route it works fine.
Thanks.
Most likely, your route is too broad. But it depends on how the rest of your routes are configured. You would need to post your entire route configuration (including area routes and attribute routing) in order to reasonably get an answer what is wrong with your route.
However, you can be more specific with this route because you know that it needs to start with /News.
routes.MapRoute(
"News",
"News/{url}",
new { controller = "News", action = "Index" }
);
Also, it probably doesn't make sense to make the URL parameter optional by providing a default value. If you remove url = "", the url parameter is required in the URL. If configured as above, if you just pass /News, it won't match this route. However, as you have it this URL will match.
Finally, make sure this route is placed in the right order. It should be placed before your default route (if you still have it).
You have set for the parameter url the empty string. you should use instead UrlParameter.Optional (or removing it at all if is mandatory):
routes.MapRoute(
"News",
"{controller}/{url}",
new { controller = "News", action = "Index", url = UrlParameter.Optional }
);
You are missing the action part in the MapRoute
routes.MapRoute(
"News",
"{controller}/{action}/{url}",
new { controller = "News", action = "Index", url = "" }
);
Hope this help

Add routing rules in MVC app

I am trying to write a rule to map a URL but so for I did not get the results I want. I have this rule so far:
routes.MapRoute(
"Search", // Route name
"{controller}/{action}/{product}/{page}", // URL with parameters
new { controller = "Home", action = "Search", product = UrlParameter.Optional, page = UrlParameter.Optional } // Parameter defaults
);
using this I can achieve this result so far:
localhost:8493/home/search/myproduct
localhost:8493/home/search/myproduct/2
but i want to do something like this:
localhost:8493/myproduct
so this will route to home/search/myproduct
I have tried the following but it didn't work:
routes.MapRoute(
"DirectSearch", // Route name
"{product}/{page}", // URL with parameters
new { controller = "Home", action = "Search", } // Parameter defaults
);
Is there a way to do this?
Add:
So Here i added the specific route to map to another action but it doesn't work:
routes.MapRoute(
"Tuna",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Tuna", id = UrlParameter.Optional }
);
You're close I think. This should work;
routes.MapRoute(
"Search", // Route name
"{product}/{page}", // URL with parameters
new { controller = "Home", action = "Search", product = UrlParameter.Optional, page = UrlParameter.Optional } // Parameter defaults
);
Just remember that the framework will read the route data from top to bottom and use the first one it finds that matches. So make sure the more specific routes are listed before the more general ones
Edit
Here's a link to a discussion on custom routing

ASP.NET MVC 2 routing: Added language, doesn't work when left away in URL

I've got some routing issues with MVC 2. Might be a simple problem, but I can't make it run. I have registered a second routing including the language:
routes.MapRoute(
// Route name
"LangRouting",
// URL with parameters
"{currentLang}/{controller}/{action}/{id}",
// Parameter defaults
new { currentLang = "de", controller = "Home", action = "Index",
id = UrlParameter.Optional }
);
routes.MapRoute(
// Route name
"Default",
// URL with parameters
"{controller}/{action}/{id}",
// Parameter defaults
new { controller = "Home", action = "Index"}
);
Now when I call {...}/de/Home/Index/ everything works fine. But if I leave the language away and call {...}/Home/Index/, the page can't be found ("The resource cannot be found."). I would have expected that this should run without language in the URL and that MVC would insert my default-value in there. How does it work else?
You must use constraint for language.
/Home/Index
will be translated into first rule as
lang = Home
controller = Index
action = Index (from defaults)
This should do the trick:
routes.MapRoute("Default with language", "{lang}/{controller}/{action}/{id}", new
{
controller = "Home",
action = "Index",
id = UrlParameter.Optional,
}, new { lang = "de|en" });
routes.MapRoute("Default", "{controller}/{action}/{id}", new
{
controller = "Home",
action = "Index",
id = UrlParameter.Optional,
lang = "en",
});

Default Controller for an Area?

This is sort of a duplicate of Trouble setting a default controller in MVC 2 RC Area
But his answer doesn't satisfy me, because it doesn't work.
I have the following
/Areas/TestArea/Controllers/HelloController
/Areas/TestArea/Views/Hello/Index
/Controllers/HomeController
/Views/Home/Index
With the following routes:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default2", // Route name
"TestArea/{controller}/{action}/{id}", // URL with parameters
new { controller = "Hello", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I added the second one to try and get http://servername/TestArea to work as if it were http://servername/TestArea/Hello but was met with no success. The basic http://servername/ works as intended.
So the question is: how do you return a default controller in an area?
Edit: I have uploaded a sample project to show what I mean: http://beginningasp.net/TestAsync.zip
Try to register Default2 route before the default route and set area=yourareaname in the default values
routes.MapRoute(
"Default2", // Route name
"TestArea/{controller}/{action}/{id}", // URL with parameters
new { controller = "Hello", action = "Index",area="TestArea", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
