Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors
you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are http://benfoster.io/blog/aspnet-mvc-custom-error-pages handled by ASP.NET and others by IIS. Ideally (and I expect http://stackoverflow.com/questions/10751363/how-do-i-make-a-generic-error-page-in-my-asp-net-application-so-that-it-handle such is the case with some other frameworks/servers) we would just configure our custom error pages in one place and it would just work, no matter how/where the error was raised. Something like:
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?

Join them; it only takes a minute: Sign up How do I make a “generic error” page in my ASP.NET application so that it handles errors triggered when serving that page itself? up vote 4 down vote favorite 2 In my ASP.NET MVC application I want to have a generic error page that is showed together with returning HTTP 500. Something like this page on Stack Overflow. Of course I'd like to reuse as much code as possible so that the page is styled the same way as other pages in my application, so I want to have an ASP.NET page reusing the master pages, not a plain HTML file. However if I do so I have a page that contains some server-side executable code for creating actual HTML served to the client. In case of Stack Overflow generic error page it's the code checking whether the user is registered, retrieving his rep, etc, and inserting elements for that into HTML. That code can fail and if that happens the page isn't properly constructed and an exception is thrown in the server. How do I handle that situation (error when building HTML for the error page) gracefully? What's the typical approach? asp.net .net iis error-handling share|improve this question edited May 25 '12 at 9:12 asked May 25 '12 at 8:54 sharptooth 109k50317708 asp.net/web-forms/tutorials/deployment/… –Jason Evans May 25 '12 at 9:14 add a comment| 2 Answers 2 active oldest votes up vote 6 down vote I like to start by categorize the possible errors. Categorize the errors. Page Not Found (this is full my log). Breaking parameters of the page by trying to hack it Error from wrong user data input. Totally Unknown error - a new bug that we must fix. a Very hard General error - nothing runs - eg, database is not opens at all. Our Goal To now show the error page, but only in rare cases. So when user make actions with out page, we try to capture all wrong input of the user, and show him what to do to continue with out any error. Global Error Handler You can start by capture on global.asax all errors using the void Application_Error(object sender, EventArgs e) void Application_Error(object sender, EventArgs e) { try { Exception Las
