Constraints in route

So I have ASP.NET MVC application. I would like to configure its routes. Here is my RouteConfig's code:
public static void Register(RouteCollection routes, bool useAttributes = true)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("favicon.ico");
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
This route works fine. Besides I have an area in my application and try to configure its routes too. It is my area registration code:
public override void RegisterArea(AreaRegistrationContext context)
{
try
{
context.MapRoute(
name: "SiteSettings_Controller",
url: "SiteSettings/{controller}/{action}/{id}",
defaults: new {action = "Index", id = UrlParameter.Optional,
// here I tried to use #"(UserManagement|Tools|Settings)"
//as constraint but it takes no effect
constraints: new {controller = "UserManagement|Tools|Settings" }
);
}
catch (Exception e)
{
// here I get InvalidOperationException ""
}
}
I would like to restrict controllers in SiteSettingsArea's route but when I go to "localhost/SiteSettings/UserManagement" url I get InvalidOperationException with message "No route in the route table matches the supplied values". I believe that this url corresponds to SiteSettings_Controller route but obviously I am wrong. How could I limit controllers in the route properly?

If you search your codebase for SiteSettings_Controller does it appear anywhere else?
The below code certainly worked for me when I just tested it.
using System;
using System.Web.Mvc;
namespace WebApplication1.Areas.SiteSettings
{
public class SiteSettingsAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "SiteSettings";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
name: "SiteSettings_Controller",
url: "SiteSettings/{controller}/{action}/{id}",
defaults: new
{
action = "Index",
id = UrlParameter.Optional
},
constraints: new { controller = "UserManagement|Tools|Settings" }
);
}
}
}

route attribute not working mvc5

[RouteArea("Admin")]
[RoutePrefix("Post")]
public class PostController : Controller
{
public ActionResult Index()
{
return View();
}
[HttpGet]
[Route("Create")]
public ActionResult Create()
{
var model = new Post();
return View(model);
}
If i'll try to access Index action it works but at Create action it doesn't. (It gives me HTTP 404)
I've added routes.MapMvcAttributeRoutes(); in RouteConfig.cs in App_Start folder
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
but after that I'm getting an error
A route named “Admin_default” is already in the route collection.
After that I need to remove that line and delete all DLL in bin folder, than rebuild project.
other I've left as it is. What's wrong?
Of course route in area is correct
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}

Route Mapping not working with "area"

I've been reading a lot about this problem, and I can't figure this out.
Everything is pretty straightforward with routing and ASP .NET MVC, but I'm stuck with this.
The problem is that I'm trying to make a GET to a given url with this form:
{area}/{controller}/{action}
But the {area} is not being registered. My default route is not working either (not working in the sense that I need to go to localhost:port/Home instead of just going to localhost:port/
This is my code:
RouteConfig:
public class RouteConfig
{
public static void RegisterRoute(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
route.MapRoute(
"Default",
"{controller}/{action}",
new {controller = "Home", action = "Index"}
);
}
}
This is the Area that is not being registered:
public class TransaccionesAreaRegistration : AreaRegistration
{
public override string AreaName
{
get{
return “Transacciones”;
}
}
public override void RegisterArea(AreaRegistrationContext context){
context.MapRoute(
"Transacciones_default",
"Transacciones/{controller}/{action}/{id}",
new { controller = "Transacciones", action = "Index", id = UrlParameter.Option}
);
}
}
Finally, this is my global.asax (I do call AreaRegistration.RegisterAllAreas() method):
protected void Application_Start(){
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
I will really appreciate some advice with this, I think I have spent enough time googling :O)

Just try this
RouteConfig:
public class RouteConfig
{
public static void RegisterRoute(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
route.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
This is the Area that is not being registered:
public class TransaccionesAreaRegistration : AreaRegistration
{
public override string AreaName
{
get{
return “Transacciones”;
}
}
public override void RegisterArea(AreaRegistrationContext context){
context.MapRoute(
“Transacciones_default”,
“Transacciones/{controller}/{action}/{id}”,
new { action = ”Index”, id = UrlParameter.Optional },
new string[] { "MyApp.Transacciones.Controllers" } // specify the new namespace
);
}
}
------------------------------OR Try This--------------------------------
public class RouteConfig
{
public static void RegisterRoute(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
AreaRegistration.RegisterAllAreas();
route.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}

Reason why default route is not working
Because you never registered a default one. Add this line in the RouteConfig -
routes.MapRoute("Home", "", new { Controller = "Home", Action = "Index" });
So the final code should look like this -
public class RouteConfig
{
public static void RegisterRoute(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
routes.MapRoute("Home", "", new { Controller = "Home", Action = "Index" });
route.MapRoute(
"Default",
"{controller}/{action}",
new {controller = "Home", action = "Index"}
);
}
}
Possible reason why Area seems not working
May be the same reason also the Area registration seems not working. Try adding the following line in area registration -
routes.MapRoute("Transacciones_Home", "Transacciones", new { Controller = "Transacciones", Action = "Index" });
So it looks like -
public class TransaccionesAreaRegistration : AreaRegistration
{
public override string AreaName
{
get{
return “Transacciones”;
}
}
public override void RegisterArea(AreaRegistrationContext context){
routes.MapRoute("Transacciones_Home", "Transacciones", new { Controller = "Transacciones", Action = "Index" });
context.MapRoute(
“Transacciones_default”,
“Transacciones/{controller}/{action}/{id}”,
new { controller = “Transacciones”, action = ”Index”, id = UrlParameter.Option}
);
}
}
}

This questions was the one that helped me.
The thing is, the order in the routes' registration is very important. Considering that, I started checking my other areas registration, and I found out that all the requests where falling into the first rule that was a general rule like this:
routes.MapRoute(
name : "Default",
url : {controller}{action}{id}
);
So, after that rule, none of the rules were being considered.
Thanks everyone for trying to help, bests!

"routes.LowercaseUrls = true;" does not work?

I'm having trouble in setting my routes to lowercase by default. For some reason it does not work. I know I can set authorize and home to lowercase myself, but the Admin part (area) will still be capitalized..
#Html.ActionLink("Hello World", "Authorize", "Home")
outputs to
Hello World
Area route
public override void RegisterArea(AreaRegistrationContext context)
{
context.Routes.LowercaseUrls = true;
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new string[] { "OR.Areas.Admin.Controllers" }
);
context.Routes.LowercaseUrls = true;
}
Default route
public static void RegisterRoutes(RouteCollection routes)
{
routes.LowercaseUrls = true;
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.LowercaseUrls = true;
routes.MapRoute(
name: "Localization",
url: "{lang}/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new string[] { "OR.Controllers" }
);
routes.LowercaseUrls = true;
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new string[] { "OR.Controllers" }
);
routes.LowercaseUrls = true;
}
Admin Area configs I tried
// admin/Home/Authorize
public override void RegisterArea(AreaRegistrationContext context)
{
context.Routes.LowercaseUrls = true;
context.MapRoute(
"Admin_default",
"{area}/{controller}/{action}/{id}",
new { area = "admin", controller = "home", action = "Index", id = UrlParameter.Optional },
new string[] { "ORMebeles.Areas.Admin.Controllers" }
);
context.Routes.LowercaseUrls = true;
}
// admin/Home/Authorize
public override void RegisterArea(AreaRegistrationContext context)
{
context.Routes.LowercaseUrls = true;
context.MapRoute(
"Admin_default",
"admin/{controller}/{action}/{id}",
new { controller = "home", action = "Index", id = UrlParameter.Optional },
new string[] { "ORMebeles.Areas.Admin.Controllers" }
);
context.Routes.LowercaseUrls = true;
}
Edit
As it seems this is bug with MVC4 - when you set context.Routes.LowercaseUrls = true; and you have Area/Areas context.Routes.LowercaseUrls = true; won't take any effect, where should we report it or how can we get it fixed?

This is bug related to MVC4 and will be fixed in MVC5 release. Routes.LowercaseUrls does not affect areas. More info here.
Meanwhile you can use LowercaseRoutesMVC or
LowercaseRoutesMVC4 if you need WebApi support.

I tried Several attempts to get this particular boolean flag to work with an MVC3 project with no luck. The ONLY way I could get it to work was to create an MVC4 application project and set the flag in the RouteConfig.cs file in the app start. The really bad part is it lowercased the urls across the site automatically for me until I added an area, then it broke everywhere. Once I excluded the newly added area from the project and reran, the urls were lowercased again.
Something is wonkey with the use of that flag. I would recommend downloading the nuget package for lowercasing urls. It seems as if they haven't quite worked out the kinks in this part of the new framework.
Sorry I couldn't be of more help.

UPDATE: IN AN MVC4 application
Create a new blank MVC4 application and add an Area Called Test, with a Test.cshtml View and a TestController.cs controller.
So I figured out something... though I am not sure if it's a reasonable solution. After playing with the route registration routines, having the areas in the project doesn't break the lowercase functionality.
namespace MvcApplication1.Areas.Test
{
public class TestAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "Test";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
//This line breaks the functionality in the area registration.
context.MapRoute(
"Test_default", // Route name
"Test/{controller}/{action}/{id}", // URL with parameters
new { controller = "Test", action = "Index", id = "" }, // Parameter defaults
new string[] { "MvcApplication1.Areas.Test.Controllers" } //namespace
);
}
}
}
A workaround:
Comment out the lines
//context.Routes.LowercaseUrls = true;
//context.MapRoute(
// "Test_default", // Route name
// "Test/{controller}/{action}/{id}", // URL with parameters
// new { controller = "Test", action = "Index", id = "" }, // Parameter defaults
// new string[] { "MvcApplication1.Areas.Test.Controllers" } //namespace
// );
In RouteConfig.cs
namespace MvcApplication1
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.LowercaseUrls = true;
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"Test_default", // Route name
"Test/{controller}/{action}/{id}", // URL with parameters
new { controller = "Test", action = "Index", id = "" }, // Parameter defaults
new string[] { "MvcApplication1.Areas.Test.Controllers" } //namespace
);
}
}
}
In The Area Controller Action Method
public ActionResult Index()
{
// Key if statement to make sure the area maps correctly
if (!this.ControllerContext.RouteData.DataTokens.ContainsKey("area"))
{
this.ControllerContext.RouteData.DataTokens.Add("area", "Test");
}
return View("Test");
}
Resulting HTML for the links in the main page of the project
<ul id="menu">
<li>Home</li>
<li>About</li>
<li>Contact</li>
<li>Test</li>
</ul>
Notice however the query string variables are not lowercased and it is not an seo friendly url. However it does find the view. This is as close as I've been able to come using that flag and having the urls go to lowercase.

As I known, LowercaseUrls = true is only available in .NET4.5, maybe you can just write some extensions for lowercase urls. you can refer to making URL lowercase. Any easy or builtin way for detail info.

Areas in asp.net mvc, only one work at time

My folder look like this:
(root)/Areas/Admin/Views/..
(root)/Areas/Admin/Controllers/...
(root)/Areas/Admin/Routes.cs
(root)/Areas/Forum/Views/..
(root)/Areas/Forum/Controllers/...
(root)/Areas/Forum/Routes.cs
public class Routes : AreaRegistration
{
public override string AreaName
{
get { return "Admin"; }
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_Default",
"{controller}/{action}/{Id}",
new { controller = "Admin", action = "Index", Id = (string)null }
);
}
}
public class Routes : AreaRegistration
{
public override string AreaName
{
get { return "Forum"; }
}
public override void RegisterArea(AreaRegistrationContext routes)
{
routes.MapRoute(
"Forum_Default",
"{controller}/{action}",
new { controller = "Forum", action = "Index"}
);
}
}
Global.asax
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
AreaRegistration.RegisterAllAreas();
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
The startpage should be Home/Index but it start with Admin/Index, why?
Only site.com/Admin works not site.com/Forum
How should i get Admin and Forum Areas to work right? Why is only Admin working and not Forum?
When i delete Admin/Routes.cs file Forum start to work...
EDIT:
Home in ~/Views/ don't show as startpage even if i have
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
in my Global.asax after AreaRegistration.RegisterAllAreas();

I believe your area mappings should be structured like so.
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_Default",
"Admin/{controller}/{action}/{Id}",
new { controller = "Admin", action = "Index", Id = (string)null }
);
}
and
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Forum_Default",
"Forum/{controller}/{action}/{Id}",
new { controller = "Forum", action = "Index"}
);
}
Keeps your routes from conflicting, which is what i think is happening in your case. As your default route matches your admin route.
