I have viewed the question Good error handling practice and it doesn't really say too much about this. asp net global 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 12.6k2791182 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

This provides the foundation on which we define the integration architecture. Global Exception Handling You can't debug a problem if you don't know that it exists. After you take your web application live, you are no longer the only one who is using it (hopefully), so you need an effective plan to track exceptions when they occur while others are surfing your site. A great way to do this is to implement an exception handler at the application level. This will allow you to consolidate the logging and notification parts of your exception handling in one convenient place. As you'll see from the code examples that follow, your global exception handler can handle both specific exceptions that you trap in your code and generic unhandled exceptions.

Implementing the Application_Error Event Handler The HttpApplication class in the System.Web namespace implements an Error event handler. This should not be confused with the HttpApplicationState class, which contains the definition for the Application object that you use in a typical ASP.NET page. You can implement this event handler in the global.asax file as shown in Listings 1 and 2.
