I have an application that I am using a global route to query for the current path and return page specific data. I have the routes setup like this...
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Pages",
"Pages",
new { controller = "Pages", action = "Index" });
routes.MapRoute(
"Navigation",
"Navigation",
new {controller = "Navigation", action = "Index"});
routes.MapRoute(
"Default", // Route name
"{*url}", // URL with parameters {controller}/{action}/{id}
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
The problem I am facing is when I go to /Pages to try and add new pages, the PageController fires like it is supposed to, but when debugging, after going to /Pages the app then makes a request for the HomeController. Am I missing something in my routing setup?
The Default route is firing because of the {*url}. So any page that's not /Pages, will go to the default route.
I need more info, but if you're trying to do /Pages/whatever, then you need to add an optional parameter on your Pages route:
routes.MapRoute(
"Pages",
"Pages/{page}",
new { controller = "Pages", action = "Index", page = UrlParameter.Optional });
Your default route is incorrect. It should look like the default route as defined when you open a new MVC 3 project, like so:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
The problem is that the default route you defined will not parse any requests which reach it.

Situation:
I have a ASP.NET application where I have different controllers. I changed in the RouteConfig the route to:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"SpecificRoute",
"{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional });
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Error", action = "NotFound", id = UrlParameter.Optional }
All pages in my the HomeController are working fine. One way I go to them is with a ActionLink:
#Html.ActionLink("Index Page", "Index", "Home")
And that works fine, even as other ways with the context as: "example", "Home".
It goes wrong when I select an other controller, let's say:
#Html.ActionLink("GoToErrorPage", "NotFound", "Error") // error page
The result of this link is that it just connects to the home page. It does not go the the correct page.
I want to connect to all pages (in other controller's too) with a URL like:
http://localhost:12345/Request
How the original url looked like (before the change in the RouteConfig)
http://localhost:12345/Home/Request
Question:
How do I need to configure the RouteConfig?
How do I set it that I don't need to type the controller before the
action in the url?
How do I set the ActionLink correct?
Both your routes are effectively the same in that they both match any url with 2 segments. If you want to be able to navigate to a method without specifying the controller name, then you will need to create specific routes for each of those methods. For example if you want to navigate to the Request(int? id) method of HomeController, with ../Request or ../Request/1 then you need
routes.MapRoute(
"Request",
"Request/{id}",
new { controller = "Home", action = "Request", id = UrlParameter.Optional }
);
and that route must be placed before the default route
Then in the view #Html.ActionLink("Request Page", "Request", "Home") will generate a url of ../Request and go the the Request() method of HomeController
In my limited (2 weeks) experience in asp.net MVC3, for most action methods, I have never needed to add a route registration. But I have noticed that if the action method has an input parameter, then I can't access the method with a url of the form www.mysite.com/myController/myAction/myParameter1/myParameter2/myParameter3 (without the ? mark ) unless I map the route. Is that how its supposed to be?
By default, you already have registered route:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
it accepts one parameter, named id, so your action:
public ActionResult MyAction(string id)
will "catch" the request:
www.mysite.com/MyController/MyAction/parameter_value
and id will get value "parameter_value".
If you need more than one parameter (or parameter has to be names something else than "id"), then you have to register new route.
In case when you have 2 parameters, you will register route like this:
routes.MapRoute(
"Default",
"{controller}/{action}/{parameter1}/{parameter2}",
new { controller = "Home", action = "Index", parameter1 = UrlParameter.Optional, parameter2=UrlParameter.Optional }
);
and your action might be:
public ActionResult MyAction(string parameter1, int? parameter2)
Yeah, you need to register the route customizing the route in global.asax according to your requirement.You have to register the route in following way:
routes.MapRoute(
"routeName", // Route name
"{controller}/{action}/{myParameter}", // URL with parameters
new { controller = "Home", action = "Index", myParameter= "" } // Parameter defaults
);
So with above route, it ensures that whenever your url goes in above format, the parameter right after "action/" will be taken as parameter.....
For more than one parameter in your url, you can register like this:
routes.MapRoute(
"routeName", // Route name
"{controller}/{action}/{myParameter1}/{myParameter2}/{myParameter3}", // URL with parameters
new { controller = "Home", action = "Index", myParameter1= "", myParameter2= "", myParameter3= "" } // Parameter defaults
);
I have the following route definitions in my MVC3 website:
routes.MapRoute(
"FB", // Route name
"fb/{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
).RouteHandler = new RH();
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
My custom "RH" handler's code is
public class RH : MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
//here I store somewhere that 'fb' prefix is used, so logic is different in some places
return base.GetHttpHandler(requestContext);
}
}
What I want to achieve, that when my website is accessed with the 'fb' subpath-prefix, then my website-logic executes a little bit different way.
The problem is, that when I access my site normally (eg. http://localhost), then when I execute
Url.Action('action' 'controller')
, then the output is "http://localhost/fb/controller/action".
I want to achieve, that when my site was accessed with 'fb' prefixed subpath, then my Url.Action calls output /fb/controller/action path, and if I access the website normally (without 'fb' prefix subpath), then Url.Action calls output /controller/action
The main thing, that /fb/controller/actions have to route to the same controllers/actions as when the site is accessed via /controller/action format.
The 'fb' route is just needed to store some temporary info when 'fb' prefix i used.
Seems I found a solution based on this link (MVC 3 Routing and Action Links not following expected contextual Route), new path-placeholder introduced and constraint added.
Maybe it's not good enough, or you know better than this, but seems to work for me:
routes.MapRoute(
"FB", // Route name
"{path}/{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new { path = "fb" }
).RouteHandler = new RH();
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I have an ActionResult in my Blog controller that is returning all the projects called Projects, but my URL looks like example.com/blog/projects, I want to set up route to make it look like example.com/projects.
Is it possible? And if it is then how can I achieve that?
You have to register route following way Global.asax and put this as a first route
routes.MapRoute("Projects", "Projects" , new { controller="blog" , action="Projects" });
You can add a route to your Global.asax.cs file, such as:
routes.MapRoute(
"Projects", // Route name
"Projects/{id}", // URL with parameters
new { controller = "Blog", action = "Projects", id = UrlParameter.Optional } // Parameter defaults
);
So it looks something like this:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Projects", // Route name
"Projects/{id}", // URL with parameters
new { controller = "Blog", action = "Projects", 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
);
}
Make sure you put your new route above the default one otherwise yours will never be hit.
Greetings,
I have a problem with link in mvc application. When I run it via Visual Studio it's ok. The link then is as follows:
http://localhost:2566/ActivateClient/Activate/6543e2d6-707d-44ae-94eb-a75d27ea0d07
when I run it via IIS7 the link is as follows:
http://localhost/ActivationService/ActivateClient/Activate/6543e2d6-707d-44ae-94eb-a75d27ea0d07
The default route is as follows:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
I assume I have to change this MapRoute, am I right? How to change it? ActivationService is my virtualDirectory in IIS. Can someone help me with this please?
I also tried to maproute as follows:
routes.MapRoute(
"Default", // Route name
"ActivationService/{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
but also without success
Did you add the new one or replace the existing one?
If you added, you need to position it before the existing one.
routes.MapRoute(
"Default", // Route name
"ActivationService/{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
The rules take precedence..
