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" }
);
}
}
}

why can I not pass a parameter in the url directly to my method in MVC (the parameter is always null)

So these are the HomeController.cs and RouteConfig.cs. When I tried to write the URL : localhost/Home/Index/Sometitle, the parameter is always null. The same thing happen when I wrote the URL : localhost/Home/Ajouter/SomeTitle. I already tried to find on the internet an answer but I had no success. Can someone tell me what's wrong or missing?

{
public class HomeController : BaseController //Controller

// GET: Home

public ActionResult Index(string title)
{
if (String.IsNullOrEmpty(title))
return View();
else
return RedirectToAction("Index", "Article", new { title = title });
}

public ActionResult Ajouter(string title)
{
if (ModelState.IsValid)
return RedirectToAction("Edit", "Article", new { title = title });
else
return View("Index");
}
}
}

//routes.MapRoute(
// name: "Wiki",
// url: "Wiki/{titre}/{action}",
// defaults: new { controller = "Wiki", action = "Index", titre = UrlParameter.Optional }
//);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
}

You need to change your parameter name to Id:
public ActionResult Index(string Id)
or replace the route with this:
routes.MapRoute(
name: "CustomName",
url: "{controller}/{action}/{title}",
defaults: new { controller = "Home", action = "Index", title = UrlParameter.Optional }
);
What I really recommand is to read more about routing in MVC

Your route must match the controller variable name try this.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{title}",
defaults: new { controller = "Home", action = "Index", title = UrlParameter.Optional }
);

Routing doesn't find controller with the same name as area

I followed article about Areas in ASP:NET MVC 4 (section How to Avoid Name Conflict). I'm using MVC 5, but I suppose all the features from version 4 are available and should work in version 5.
My directory structure:
File EpicAreaRegistration.cs content:
namespace App1.Web.UI.Areas.Epic
{
public class EpicAreaRegistration : AreaRegistration
{
public override string AreaName
{
get{ return "Epic"; }
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRouteLocalized(
name: "Epic_default",
url: "Epic/{controller}/{action}/{id}",
defaults: new { controller = "Pm", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "App1.Web.UI.Areas.Epic.Controllers" }
);
}
}
}
My project's App_Start -> RouteConfig.cs file content: UPDATE corrected namespace
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Default", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "App1.Web.UI.Controllers" } // according to article namespace must be added here, so ASP.NET router distinguishes between request: e
);
}
}
And finally I have EpicController.cs file in project's directory Controllers:
namespace App1.Web.UI.Controllers
{
public class EpicController : Controller
{
public ActionResult Browse()
{
return View();
}
}
}
When I navigate to: http://localhost:7300/Epic/Pm it works (finds it), but http://localhost:7300/Epic/Browse doesn't work (404 - not found). What have I missed?
My assumption is that request goes through some kind of routing table. If it doesn't find Epic/Browse in Areas, it should move to project's root Controller folder. It's the same analogy as with Views (folder, if not in folder look in Shared, ...)
Additionally I registered all areas in Application_Start
public class Global : HttpApplication
{
void Application_Start(object sender, EventArgs e)
{
AreaRegistration.RegisterAllAreas();
GlobalConfiguration.Configure(WebApiConfig.Register);
RouteConfig.RegisterRoutes(RouteTable.Routes);
....

Make sure your Area controller uses the correct namespace.
Namespace for EpicController is currently:
namespace App1.Web.UI.Controllers
Change it to:
namespace App1.Web.UI.Areas.Epic.Controllers

Your controller is also Epic. So your URL would look like
http://localhost:7300/Epic/Epic/Browse

This may help you to access,
http://localhost:7300/Areas/Epic/Epic/Browse
As It's contained in sub folder.

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!

Not able to route to a view under area in MVC Razor

Problem Statement:
I'm trying to route to a Login view under Area(Test Area) not working.
Exception:
HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this directory
Most likely causes:
A default document is not configured for the requested URL, and directory browsing is not enabled on the server.
If I route to view other than the login view under area it works fine
What I'm doing wrong in routing??
Area:
Test Area Registartion.cs
public class TestAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "Test";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Test_default",
"Test/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
}
Roue Config in App_Start :
If I use default route for login it works fine ,but if I give route to login view under test area it gives HTTP Error 403.14 - Forbidden The Web server is configured to not list the contents of this director why??
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
// Default Route for Login
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
);
//Area View Route for Login
routes.MapRoute(
name: "Test",
url: "Test/{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "WebApplication1.Areas.Test.Controllers" }
);
}
}
Global.asax.cs :
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
Database.SetInitializer<WebApplication1.Areas.Test.Models.Test_DB>(null);
}

Try with this:
routes.MapRoute(
name: "Test",
url: "{controller}/{action}/{id}",
defaults: new {controller = "Login", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "WebApplication1.Areas.Test.Controllers" }).DataTokens["area"] = "Test";
