I have some problems using Areas in my MVC project. I'm able to access my controller, which is located under the area, but when it returns to view (with model), I get an error:
The view 'Index' or its master was not found or no view engine
supports the searched locations.The following locations were searched:
~/Views/MyController/Index.aspx ~/Views/MyController/Index.ascx etc.
Here is the MyAreaAreaRegistration:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"MyArea_default",
"MyArea/{controller}/{action}/{id}",
new { controller = "MyController", action = "Index",
id = UrlParameter.Optional });
}
Routeconfig:
routes.MapRoute(
name: "Default", // Route name
url: "{controller}/{action}/{id}", // URL with parameters
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "MyApp.Controllers" }
);
Global.asax:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
...
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
And controller:
return View(myViewModel);
I'm totally stuck with this one. Any help would be much appreciated.
Please change your route config code .
routes.MapRoute(
name: "Default", // Route name
url: "{controller}/{action}/{id}", // URL with parameters
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
).DataTokens.Add("area", "MyArea"); ;
It will be work for you .
Thanks .

I'm working in MVC 5 and have taken over a project. When I log onto the homepage "mydomain.com" it comes up with an error:
"Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. Requested URL:/"
If I type in mydomain.com/home/index it comes up with the home page as it should. I figure this is a RouteConfig.cs problem, but everything looks pretty default to me.
namespace Source
{
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 = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Glossary2",
url: "{controller}/{action}/{letter}",
defaults: new { controller = "Teacher", action = "Glossary2", letter = UrlParameter.Optional }
);
/* Will need to finish this later.
* When the contact us form is submitted, it should redirect to Home/Contact/{state}
* where {state} can be either 'Success' or 'Error', which will display
* an alert component in the view based on the provided {state}.
*/
routes.MapRoute(
name: "ContactSuccess",
url: "{controller}/{action}/{submissionStatus}",
defaults: new { controller = "Home", action = "Contact", submissionStatus = UrlParameter.Optional }
);
/* Will need to finish this later.
* When the contact us form is displayed, it should check to see if a reason for contacting
* us is already set. If it is, it should automatically select the appropriate reason on the
* dropdown menu.
*/
routes.MapRoute(
name: "ContactReason",
url: "{controller}/{action}/{reason}",
defaults: new { controller = "Home", action = "Contact", reason = UrlParameter.Optional }
);
}
}
}
I'm not sure what the CustomeViewEngine is doing and haven't really messed around with it yet. I've also inspected the Global.asax.cs file and it looks pretty standard as well.
namespace Source
{
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ViewEngines.Engines.Add(new CustomViewEngine());
}
}
public class CustomViewEngine : RazorViewEngine
{
public static readonly string[] CUSTOM_PARTIAL_VIEW_FORMATS = new[]
{ "~/Views/Selection/{0}.cshtml" };
public CustomViewEngine()
{
base.PartialViewLocationFormats = base.PartialViewLocationFormats.Union(CUSTOM_PARTIAL_VIEW_FORMATS).ToArray();
}
}
}
Is there a way to trace down why the domain name is not getting routed to home/index? If I put the Default mapping at the bottom of the RouteConfig file it wants to automatically direct to the login page. Again, I'm not really understanding why this would be acting this way.
I think your route definitions are not in right order, the route order evaluates from top to bottom (the most specific path resolved first).
Hence, the default route should be take place as the last defined route:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// custom path at the top (or top-most depending on priority)
routes.MapRoute(
name: "Example",
url: "Example/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
// default path at the bottom-most
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Additionally, all URLs defined in every route in the sample are in same pattern (using {controller}/{action}/{parameter}), hence it potentially conflict between each other. You can use plain strings to differentiate similar route patterns:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Glossary2",
url: "Teacher/{action}/{letter}",
defaults: new { controller = "Teacher", action = "Glossary2", letter = UrlParameter.Optional }
);
routes.MapRoute(
name: "ContactSuccess",
url: "{controller}/{action}/SubmissionStatus/{submissionStatus}",
defaults: new { controller = "Home", action = "Contact", submissionStatus = UrlParameter.Optional }
);
routes.MapRoute(
name: "ContactReason",
url: "{controller}/{action}/Reason/{reason}",
defaults: new { controller = "Home", action = "Contact", reason = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Note: Use RouteDebugger to find out which routes handled by RouteConfig when accessing specific routes.
I created two areas (with controllers, views, registration, etc) with VS's scaffolding process. One for homecontroller and one called account.
I added a single line "route.DataTokens" to the routeconfig.cs file to connect to the homecontroller on startup.
var route = routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional }
);
route.DataTokens["area"] = "Home";
Here is my HomeAreaRegistration.cs RegistrationArea method
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Home_default",
"Home/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
But in the url of the browser I see
https://localhost:44301/Home/Home/Index
What I want to see is
https://localhost:44301/Home/Index
What do I modify to get this?
Edit - Solved! I think.
Here is what I did.
In HomeArearegistration.cs I removed the Home/
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Home_default",
"{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
Is this the proper way to go about doing this because something doesn't seem right here, if I type
https://localhost:44301/Home/Index.cshtml
which I would expect to take me to the home page, I get a HTTP 404 error not found but if I type
https://localhost:44301/Home/Index
It take me to the home page
I am using mvc4 framework and .net framwork 4.5. I need a url like this:
www.examples.com/name (note: 'name' will be change dynamically)
which routes to the same page.
I have tried like this but getting error
My action method is like this:
public ActionResult Userlist(string status)
{
return View();
}
Route Config
routes.MapRoute(
"user",
"{status}",
new { controller = "Home", action = "Userlist" }
);
How can I create a route syntax and redirect this to a controller?
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// Add this route config
routes.MapRoute(
name: "Default_Userlist",
url: "{status}",
defaults: new { controller = "Home", action = "Userlist" },
namespaces: new[] { "MyMvcProject.Controllers" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "MyMvcProject.Controllers" }
);
}
Don't forget to replace the "MyMvcProject" with the name of your project.
Issue
This is a bad practice because the value of the status could easily cause conflicts with your action methods.
please I need help with this scenario:
I have an Area "\UI" with one Controller "ActionController" and his View "Login.cshtml" also in his UIAreaRegistration class:
public class UIAreaRegistration : AreaRegistration
{
public override string AreaName
{
get { return "UI"; }
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"UI_default",
"UI/{controller}/{action}/{id}",
new { controller = "Account", action = "Login", id = UrlParameter.Optional }
);
}
}
Now I want Login.cshtml to be the first view of the app.
Then in 'RegisterRoutes' of global.asax.cs I have:
AreaRegistration.RegisterAllAreas();
//Default
//routes.MapRoute(
// name: "Default",
// url: "{controller}/{action}/{id}",
// namespaces: new[] { "", "" },
// defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
//);
routes.MapRoute(
name: "Default",
url: "{area}/{controller}/{action}/{id}",
defaults: new { area = "UI", controller = "Account", action = "Login", id = UrlParameter.Optional }
);
But didn't work, please what should I do?
Thanks in advance
What you are trying to do is to make your UI area a default area, so any controller in UI will be accessible without UI prefix in URL.
The problem with that is that the controllers which are in root folder will no longer be accessible. If it is what you want you can do it by changing the area route registration from :
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"UI_default",
"UI/{controller}/{action}/{id}",
new { controller = "Account", action = "Login", id = UrlParameter.Optional }
);
}
to:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"UI_default",
"{controller}/{action}/{id}",
new { controller = "Account", action = "Login", id = UrlParameter.Optional }
);
}
Easier solution will be to create an action on the default controller which will redirect user to your area
Area folders look like :
Areas
Admin
Controllers
UserController
BranchController
AdminHomeController
Project directories look like :
Controller
UserController
GetAllUsers
area route registration
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
new { controller = "Branch|AdminHome|User" }
);
}
project route registration
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new string[] { "MyApp.Areas.Admin.Controllers" });
}
When I route like this: http://mydomain.com/User/GetAllUsers I get resource not found error (404). I get this error after adding UserController to Area.
How can I fix this error?
Thanks...
You've messed up your controller namespaces.
Your main route definition should be:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new string[] { "MyApp.Controllers" }
);
And your Admin area route registration should be:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
new { controller = "Branch|AdminHome|User" },
new[] { "MyApp.Areas.Admin.Controllers" }
);
}
Notice how the correct namespaces should be used.
