How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 This code example shows how to create an error handler in the Global.asax file that will catch all unhandled ASP.NET errors while processing a request — in other words, all the errors that asp net global variable are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site. C#VB Copy void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs // Get the exception object. Exception exc = Server.GetLastError(); // Handle HTTP errors if (exc.GetType() == typeof(HttpException)) { // The Complete Error Handling Example generates // some errors using URLs with "NoCatch" in them; // ignore these here to simulate what would happen // if a global.asax handler were not implemented. if (exc.Message.Contains("NoCatch") || exc.Message.Contains("maxUrlLength")) return; //Redirect HTTP errors to HttpError page Server.Transfer("HttpErrorPage.aspx"); } // For other kinds of errors give the user some information // but stay on the default page Response.Write("

I have viewed the question Good error handling practice and it doesn't really say too much about this. My experience has been excluding some very specific circumstances (such as transactions) most of the asp net global ASP.NET applications we are writing are along the lines of void ButtonEventHandler(object sender, EventArgs e) { Page.Validate(); if (Page.IsValid) { //Do a database insert or update thru relevant datalayers. //If its a transaction then we rollback internally and rethrow //the exception. } } Why not just have a global exception handler? Usually (at this point) the only thing I can do is abort the operation gracefully and tell the user to try again. c# asp.net error-handling share|improve this question asked Oct 24 '11 at 12:55 Maxim Gershkovich 12.6k2791182 stackoverflow.com/questions/155203/good-error-handling-practice –ChrisBint Oct 24 '11 at 13:02 At the same point, I usually catch known possible exceptions and display a message to the user, leaving unexpected exceptions for global handling. You could catch all exceptions (most people argue against this) and display a message as long as you've logged the exception. If you don't log the exception, it will be a huge pain to track down the error. You may spend weeks trying to reproduce an error caused by a rare database/services hiccup. –Jim Schubert Oct 24 '11 at 13:06

An article on how to gracefully trap application errors in asp.net applications Download demo project - 13.1 Kb Introduction No matter how great your application is at handling errors, there could still be a time when an application throws an error that is unhandled. Default web.config settings will have the customerrors tag set to Off, in which you get the typical ASP.NET error page that is very helpful as a developer because it usually points us in t
