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 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.

Currently, what I want to do is to handle specific exceptions that I am positively sure I can handle. On the other hand, I want to terminate the application if an exception that I dont know how to handle is thrown. When I place try-catch net error handling blocks in my source code, it looks ugly because there are many of those. Is there a global exception handling mechanism like an event that is fired once an unhandled exception is thrown? That way I can display an error message to the user and terminate the application instead of reiterating this process over and over throughout my source code. P.S. I want to terminate the application in such a scenario because I am afraid the program might begin functioning improperly once an unhandled exception is thrown. exception-handling share|improve this question asked Jul 9 '10 at 8:02 user246392 1,13952447 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted At least in C# you can assign a global "unhandled exception handler". To do this, you'd assign a new handler to AppDomain.CurrentDomain.UnhandledException. share|improve this answer answered Jul 9 '10 at 8:14 Thorsten Dittmar 40.5k25595 I see that the event handler kills the process. I want to show a user control and have it terminate the application, but the user control is not shown. The only thing I can display is a message box.

Join them; it only takes a minute: Sign up Global error handling in ASP.NET up vote 8 down vote favorite 2 Is there anything wrong with catching errors in an ASP.NET application globally (eg: Global.asax)? 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 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 12.8k2793185 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 add a comment| 2 Answers 2 active oldest votes up vote 5 down vote accepted The global place to handle uncatched Exceptions would be in Global.asax by handling Application_Error. As John pointed out, you should always handle exceptions as close as possible to where they might occur and react appropriately. share|improve this answer answered Oct 24 '11 at 13:26 Icarus 45.7k85486 But hold on, my point is this.... Yes of course if I can somehow handle the exception at the source I will do so but typically the only action that
