How to: Handle Page-Level Errors Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 If possible, you should handle errors in Try/Catch blocks within your asp.net mvc error handling code, because a problem is more easily corrected where it occurs. If the user can help correct a problem, the page needs to return to the same place so the user has a context for understanding what to do. A page-level handler returns you to the page, but there is no longer anything on the page because instances of controls are not created. To provide the user any information, you must specifically write it to the page. You would probably use a page-level error handler to log unhandled errors or to take the user to a page that can display helpful information. This code example shows a handler for the Error event in an ASP.NET Web page. This handler catches all exceptions that are not already handled within Try/Catch blocks in the page. After you handle an error, you must clear it by calling the ClearError method of the Server object (HttpServerUtility class). Example This handler filters for specific kinds of exceptions. For an ArgumentOutOfRangeException exception, the handler writes some text on the page, provides a link back to the page, logs the error
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 by IIS. Ideally (and I expect asp.net application_error such is the case with some other frameworks/servers) we would just configure our asp.net page_error 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? 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 workings and policies of this site About Us Learn more about Stack Overflow http://stackoverflow.com/questions/2161413/implementing-a-custom-error-page-on-an-asp-net-website the company Business Learn more about hiring developers or posting ads with us Stack https://www.stokia.com/support/misc/web-config-custom-httperrors.aspx Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 6.2 million programmers, just like you, helping each other.

I put the following code in my web.config
your web site. The custom errors can be set or overridden on a site wide or directory-by-directory basis. While some web.config sections require that the directory is set as an application, this isn't one of them. A simple web.config with a httpErrors section may be placed in any directory, and the directory does NOT need to be set as an application. What are http errors? HTTP errors are returned to the client when something goes wrong on the server. Error status codes are returned if the requested file isn't found (404), or due to coding errors in the web page (500), and due to temporary issues such as failed database connections (500). The most common errors are 404 (file not found) and 500 (application) errors. Custom 404 and 500 errors are typically used to provide a friendlier error message to your users. Custom 404 and 500 errors could also redirect the user to the default (or any) page, and are sometimes used to notify the web site administrator of problems on the web site. If you wish to configure custom errors for your site, or even just for a single directory in your site, please follow the directions on this page. 400 Error (bad request) 401 Error (unauthorized) 403 Error (forbidden) 404 Error (not found) 500 Error (internal server error) How it's done Example custom HTTP errors.
