ASP.NET MVC 5 Custom Error Pages Doesn't Work

Question

I've set up my webconfig to custom error pages. But it doesn't work. I create a controller and action with name "hata". I can see this page "http://localhost/hata/bulunamadi" but when i try to open not exists page so my custom error pages doesn't show. (i see iss default 404 page)

<system.web> 
<customErrors defaultRedirect="~/hata/bulunamadi" redirectMode="ResponseRewrite" mode="On">
 <error statusCode="404" redirect="~/hata/bulunamadi"/>
</customErrors>
</system.web>

• KrishnaDhungana: Custom Error relies on ErrorController. How does it look like?

Answer 1

<customErrors mode="On" defaultRedirect="~/Error">
 <error redirect="~/Error/NotFound" statusCode="404" />
</customErrors>

And the controller contains the following:

public class ErrorController : Controller
{
 public ViewResult Index()
 {
 return View("Error");
 }
 public ViewResult NotFound()
 {
 Response.StatusCode = 404; //you may want to set this to 200
 return View("NotFound");
 }
}

Answer 2

try this

Web.Config

 <system.web>
 <customErrors mode="On" defaultRedirect="Error">
 <error statusCode="404" redirect="NotFound" />
 </customErrors> 
</system.web>

create Error.cshtml and NotFound.cshtml in shared folder Create an ErrorController

 public ActionResult Error()
 {
 return View();
 }

Please follow step by step this description : First, you have to settings up your web config for custom page error. Just like this

<system.web>
 <customErrors mode="On" defaultRedirect="~/Error/" redirectMode="ResponseRedirect">
 <error statusCode="404" redirect="~/Error/Error404/" />
 <error statusCode="500" redirect="~/Error/Error500/" />
 <error statusCode="400" redirect="~/Error/Error400/" />
 </customErrors>
</system.web>

Then you have to configure your RouteConfig.cs :

routes.MapRoute(
 name: "Default",
 url: "{controller}/{action}/{id}",
 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
 "404-PageNotFound",
 "{*url}",
 new { controller = "Error", action = "Error404" }
);

And finally, you have to create your custom error View and Action :

public class ErrorController : Controller
 {
 // GET: Error
 public ActionResult Index()
 {
 return View();
 }
 public ViewResult Error404()
 {
 return View();
 }
 public ViewResult Error500()
 {
 return View();
 }
 public ViewResult Error400()
 {
 return View();
 }
 public ActionResult General()
 {
 return View();
 }
 }
