I am developing an ASP.NET MVC application. Content is divided into several areas:
Scheme - for shared functionality like errors
Pages - for displayed content
Data - for controllers, that returns JSON data
I don't have any controllers not assigned to areas.
I would like to access Pages controllers without typing area's name, and other to be accessed with their area names in route.
So I want to display action Users in Administration page under host/Administration/Users
And I want to display DatabaseTimeout Action from Error controller under host/Scheme/Error/DatabaseTimeout.
Analogously I want Create action from Codes controller from Data area under host/Data/Codes/Create.
Now, the problem: Pages area works as expected, Data area works as expected, Scheme area doesn't work as expected. When typing host/Scheme/Error/DatabaseTimeout application returns a 404.
Can anyone tell me what is wrong?
Here is part of application code:
Global.asax:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
RouteConfig.cs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
}
DataAreaRegistration.cs
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Data_default",
"Data/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "MyWebApplication.Areas.Data.Controllers" }
);
}
PagesAreaRegistration.cs:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Pages_default",
"{controller}/{action}/{id}",
new { controller="Home", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "MyWebApplication.Areas.Pages.Controllers" }
);
}
SchemeAreaRegistration.cs:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Scheme_default",
"Scheme/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "MyWebApplication.Areas.Scheme.Controllers" }
);
}
AdministrationController.cs from Pages area:
namespace MyWebApplication.Areas.Pages.Controllers
{
public class AdministrationController : Controller
{
// action methods...
}
}
CodesController.cs from Data area:
namespace MyWebApplication.Areas.GridData.Controllers
{
public class CountryCodesController : Controller
{
// action methods...
}
}
ErrorController.cs from Scheme area:
namespace MyWebApplication.Areas.Scheme.Controllers
{
public class ErrorController : Controller
{
// action methods...
}
}
EDIT:
Ok, now I am really confused.
So under Scheme area I have, among others:
- _Layout.cshtml file, wchich is master page for every showed page
- Menu.cshtml, which is view for Menu action and is rendered on _Layout
Menu view is rendered by:
#{Html.RenderAction("Index", "Menu", new { area="Scheme" });}
Menu is rendered fine, however...
In menu there is many action links, that directs into different pages, written like this:
#Html.ActionLink("Manage users", "Users", "Administration", new { area = "Pages" }, null)
And that gives route like this: host/Scheme/Administration/Users
Eventhough area was specified. I tried to change area parameter into area="", did't help.
Please help me, I am confused and I cant go further with my work. :(
When you type host/Scheme/Error/DatabaseTimeout probably application returns a 404 because you don't have a action DatabaseTimeout in ErrorController.cs in Scheme area:
namespace MyWebApplication.Areas.Scheme.Controllers
{
public class ErrorController : Controller
{
public ActionResult DatabaseTimeout()
{
return View();
}
}
}
You must create the view ,where you show the error at the user, in your project under Areas\Scheme\Views\Error\DatabaseTimeout.cshtml.
The other question --> i think that if you want create a link to action Index() in HomeController under Schemearea you must use this in the views:
#Html.ActionLink("Home", "Index", "Home", new { area = "Scheme" }, null)

I have area BackOffice, controller BrandController and action Edit. I want to route following URL to this action: /BackOffice/Brand/Act/Manage
The URL is fixed, none of the elements shall be changeable. How can I do that using MapRoute ?
In the AreaRegistration class for BackOffice:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
null,
"/BackOffice/Brand/Act/Manage",
new { controller = "Brand", action = "Edit" }
);
}
I am working on a new project and i have decided to use attribute routing alone. This is my RouteConfig file:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
//routes.MapRoute(
// name: "Default",
// url: "{controller}/{action}",
// defaults: new { controller = "HomeController", action = "Index", id = UrlParameter.Optional }
//);
}
This is my controller:
[RoutePrefix("home")]
public class HomeController : Controller
{
[Route]
[Route("~/")]
public ActionResult Index()
{
var status = HttpContext.User.Identity.IsAuthenticated;
ViewBag.Title = "Home Page";
return View();
}
[Route("test")]
public ActionResult Test()
{
return View();
}
}
I've realised that typically all my attributes are working but i want the Index method to run on application start. Say https://example.com and then the Index method is fired as if i entered the url https://example.com/home/index. I get a blank space when i do say https://example.com.
Can anyone please help me understand why i get a blank space and also how to set the default application start route using attribute routing? I've been surfing the internet for hours but i can't lay my hands on anything.
In your case you should still set a default route. That way the site knows where to start. From there everything else should work as you intended.
public static void RegisterRoutes(RouteCollection routes) {
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{action}",
defaults: new { controller = "Home", action = "Index" }
);
}
Here is my Home Controller.
public class HomeController : FrontOfficeControllerBase {
public HomeController() {
}
public ActionResult Index() {
...
return View();
}
}
Other than that this keeps my route config clean as I use attribute routing everywhere else.
Try this:
[RoutePrefix("home")]
public class HomeController : Controller
{
[Route("index")]
[Route("~/", Name = "default")]
public ActionResult Index()
{
...
}
...
}
In Asp.net MVC4 I have created below URL showing 404 error with IIS8.0
http://{ParentURL}/Areas/Admin/Menu/Index?actoin=Add
Please help me on it.
You URL http://{ParentURL}/Areas/Admin/Menu/Index?mode=Add goes to:
Area: Admin
Controller: Menu
Action + View: Index
Parameter: mode
So in MenuController.cs (under Admin area) you should have this:
public ActionResult Index(string mode)
{
//code
return View();
}
UPDATE:
Change your URL to: http://{ParentURL}/Admin/Menu/Index?mode=Add
The parameters of your Action must have the same name as in your route declaration.
Also another mistake is to use Areas in your URL, you can remove it or change your default route.
Controller:
public ActionResult Index(string mode)
{
return View(ViewMenuModel);
}
View:
var JsSuccessAction = '#Url.Content("~/Admin/Menu/Index?mode=Add")';
Route:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute( "Admin_default", "Admin/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } );
}
You need to set a route in route config :
context.MapRoute(
"Areas",
"Areas/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
add this to your root config and try .. will work
I have a controller defined in a library. I'd like this controller to be accessible via any of my 3 areas. At the moment, the controller (let's say "contact") is not being found when accessed via for example the "admin" area (i.e. url of /admin/contact). It does however work when accessed via "/contact".
Is there any route configuration required to Areas in order to allow the access of a common controller though these areas?
Thanks.
You could put this controller in a namespace:
namespace MvcApplication1.Controllers.MyAreas
{
public class ContactsController : Controller
{
...
}
}
and then in your area registration specify this namespace:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Admin_default",
"Admin/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional },
new[] { "SomeLibrary.Controllers.MyAreas" }
);
}
Now when you navigate to /admin/contacts/index the Index action of the ContactsController will be executed.
I'm having trouble finding the answer to this question anywhere.
I am in need of creating a form where the user can create a post and change the url to the post.
For example, if the default route is
http://www.domain.com/posts/[the-title-of-the-post]
The user can change this to
http://www.domain.com/[modified-title-of-the-post].
The [modified-title-of-the-post] can be anything the user would like to make it.
This means it is no longer tied to the title of the post and not only that, but the /posts/ is gone too.
I guess I should Also mention that this should be global, meaning the user should be able to change the url (as mentioned above) for other things on the sites like, /topics/ or /blog/
Any help would be greatly appreciated,
Thanks,

You could create two routes in your global.asax. Something like this
routes.MapRoute("", "posts/{url}", new { controller = "Home", action = "Posts" });
routes.MapRoute("", "{url}", new { controller = "Home", action = "Posts" });
both of them point to HomeController and the action Posts
public ActionResult Posts(string url)
{
}
to handle every url you should consider to extend the RouteBase class
Something like that should do
public class CustomRouting : RouteBase
{
public override RouteData GetRouteData(HttpContextBase httpContext)
{
RouteData result = null;
string requestUrl = httpContext.Request.AppRelativeCurrentExecutionFilePath;
//Handle the request
//Compile the RouteData with your data
result = new RouteData(this, new MvcRouteHandler());
result.Values.Add("controller", "MyController");
result.Values.Add("action", "MyAction");
result.Values.Add("id", MyId);
}
}
return result;
}
public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
{
//I only need to handle outbound so here is ok
return null;
}
}
The in your global.asax you register your custom route handler
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.Add(new CustomRouting());
routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional });
}
