Mvc 5 Custom Error Page
Join them; it only takes a minute: Sign up Handling route errors in ASP.NET MVC up vote 5 down vote favorite 2 I understand how to set up my own routes, but how does one handle routes that fall through the cracks of the routing table? I mean, I guess the default {controller}/{action}/{id} route could be a generic asp.net mvc handleerrorattribute catchall, but I'm not sure if that's the way to go. I like letting my users know they've requested data/a 'page' that doesn't exist. Is this where the [HandleError] filter comes in? How does that work, exactly? asp.net-mvc routes share|improve this question edited Jan 28 '11 at 20:49 Tim Cooper 87.1k21162181 asked Jan 28 '11 at 20:47 Major Productions LLC 3,774545104 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted If your route is not found, you want to handle it as a normal HTTP 404 error. If you only add the [HandleError] attribute to your class or action, MVC will look for an Error view in your views folder. You could also add an ErrorController or even a static page and add this to your Web.config:

error logging are two elementary and yet very confusing topics in ASP.NET MVC 5. There are numerous ways of implementing global error handling in mvc error pages in ASP.NET MVC 5 and when you search for advice you will find a dozen different StackOverflow threads, each suggesting a different implementation. Overview What is the goal? Typically good error http://stackoverflow.com/questions/4832906/handling-route-errors-in-asp-net-mvc handling consists of: Human friendly error pages Custom error page per error code (e.g.: 404, 403, 500, etc.) Preserving the HTTP error code in the response to avoid search engine indexing Global error logging for unhandled exceptions Error pages and logging in ASP.NET MVC 5 There are many ways of implementing error handling in ASP.NET MVC 5. Usually you will find solutions which involve at https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging least one or a combination of these methods: HandleErrorAttribute Controller.OnException Method Application_Error event customErrors element in web.config httpErrors element in web.config Custom HttpModule All these methods have a historical reason and a justifyable use case. There is no golden solution which works for every application. It is good to know the differences in order to better understand which one is applied best. Before going through each method in more detail I would like to explain some basic fundamentals which will hopefully help in understanding the topic a lot easier. ASP.NET MVC Fundamentals The MVC framework is only a HttpHandler plugged into the ASP.NET pipeline. The easiest way to illustrate this is by opening the Global.asax.cs: public class MvcApplication : System.Web.HttpApplication Navigating to the implementation of HttpApplication will reveal the underlying IHttpHandler and IHttpAsyncHandler interfaces: public class HttpApplication : IComponent, IDisposable, IHttpAsyncHandler, IHttpHandler ASP.NET itself is a larger framework to process incoming requests. Even though it could handle incoming requests from different sources, it is almost exclusively used with IIS. It can be extended with HttpModules and HttpHandlers. HttpModules are plugged into the pipeline to process a request at any point of the ASP.NET life
MVC, we want to handle and respond to errors utilizing HTTP Errors: 400, 404, 500, etc. This post will show you how http://www.khalidabuhakmeh.com/creating-error-routes-for-asp-net-mvc-and-restful-routing to create the routes required to show a friendly error message. While this tutorial will give you all you need, I recommend searching for other tutorials about setting up your customErrors http://setiabud.blogspot.com/2013/04/handling-404-error-in-aspnet-mvc.html configuration more thoroughly. Routes.cs / RoutesConfig The heart of Restful Routing lives in the RouteSet class. You always start off with one. If you installed Restful Routing via Nuget it will asp.net mvc be the Routes.cs file. It looks like this. public class Routes : RouteSet { public override void Map(IMapper map) { map.DebugRoute("routedebug"); } public static void Start() { var routes = RouteTable.Routes; routes.MapRoutes
a web.config setting. In ASP.NET MVC, it is a bit more complicated. Why is it more complicated? In comparison, everything is seemingly easier in MVC than WebForm. It is more complicated mainly because of Routing. In WebForm, most 404 occurs because of non-existent file and eachUR: is usually mapped to a particular file (aspx). With MVC, that is not the case. All requests are handled by the Routing table and based on that it will invoke appropriate controller and actions etc. Secondly, our basic default route usually is quite common ({controller}/{action}/{id}) - therefore most URL request will be caught by this route. So, let's dive in on how can we do proper handling of 404 errors with ASP.NET MVC. TURN ON CUSTOM ERROR IN WEB.CONFIG
