Asp.net Mvc Common Error Page
Contents |
you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are handled by ASP.NET and others aspnet mvc nuget by IIS. Ideally (and I expect such is the case with some aspnet mvc source other frameworks/servers) we would just configure our custom error pages in one place and it would just work, no aspnet mvc tutorial matter how/where the error was raised. Something like:
Aspnet Mvc 5
static or dynamic) we should return a 404 HTTP status code. Ideally we should return something a little friendlier to our site visitors than the error pages built in to ASP.NET/IIS, perhaps offering some advice on why the resource may not exist or providing an option to search the site. For the purposes of this blog post, my custom 404 page aspnet mvc 4 is very simple, but you can see some really nice examples here.
404 Page Not Found
I created a new ASP.NET MVC 5 application using the standard template in Visual Studio. If I run the site and try to navigate to a resource that does not exist e.g. /foo/bar, I'll get the standard ASP.NET 404 page with the following information: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /foo/bar Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.33440 Not exactly friendly, is it? In this case the error was raised by ASP.NET MVC because it could not find a matching controller and/or action that matched the specified URL. In order to set up a custom 404 error page add the following to web.config insidehere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the aspnet mvc cms workings and policies of this site About Us Learn more about Stack

the default HandleError Attribute in MVC. In this article, we will see how we can use the HandleError attribute to quickly put together an exception handling mechanism that helps hide the ‘dark' underbelly of your application but helps you debug with the same configuration. We will also look at a solution to handle 404 errors gracefully. Overall we try to achieve the following on IIS 7+ Goal 1 - Use MVCs HandleError action filter to take care of Unhandled/Unexpected errors Goal 2- See only user friendly messages at Runtime Goal 3 - See exception stack traces at debug time Goal 4- Manage 404 error with a proper error message Goal 5 - Keep a 404 Response status The HandleError Attribute The HandleError attribute helps mark controller classes for ‘Unhandled Error' exceptions. The HandleErrorAttribute() attribute filter will pipe the Unhandled exceptions to this attribute filter enabling you to take appropriate exception. The attribute filter is put in place by the default MVC template in the Global.asax (or for MVC4 in the App_Start\FilterConfig.cs) by adding the Action filter as follows: public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); } By default, if you turn on CustomErrors, the behavior of the HandleErrorAttribute is to redirect you to the default Error page. Setting up the Custom Errors page Setup of the Custom Errors page is easy. We simply turn on the CustomErrors in the web.config. To Test the setting we throw an exception in the ‘About' action method of the Home Controller public ActionResult About() { ViewBag.Message = "Your app description page."; throw new ApplicationException("Testing default ErrorHandler attribute"); //return View(); } Now when we run the application and click on ‘About' we see the following This is the default output from Errors.cshtml in the Shared folder of a default MVC project. As we can see, it returns a correct 500 status message. At this stage, we have achieved the first and second goals we set out to achieve. However we have lost the stack trace. Let us fix that without loosing out on the current behavior. Updating Error Page to show stack trace - Open the Error.cshtml and update it as follows This change will ensure we see a stack trace. But as of now, this is no better than the Yellow Screen of Death because End Users are going to see it as well. We have lost our second goal of presenting User Friendly error messages. To fix that problem, we use the Request.IsLocal property that tells us if the
