Application error handling in ASP.NET Download demo - 269.4 KB Introduction When an unhandled exception occurs in my application, I want my application to give the user a "graceful" response. Regardless of the error, I do not want the user to see an unfriendly technical error messages generated by IIS or ASP.NET. At the same time, I want to receive email notification for every unhandled exception. This article describes a simple and comprehensive solution to this problem. The Problem When I have no error handling configured for my application, my users might see any one of three different error pages, depending on the type of error. If a user requests a static resource that does not exist (for example, an HTML or J

How to: how to raise Create ASP.NET Application-Level Event Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 ASP.NET automatically binds application events to event-handler methods in the Global.asax file using a naming convention of Application_event, such as Application_BeginRequest and Application_Error. For more information, see ASP.NET Application Life Cycle Overview for IIS 5.0 and 6.0. This code example handles the application-level Error event and writes error information to the system event log. The Error event is raised whenever an application error or unhandled page error occurs. To create an Asp.NET application-level event handler If your Web site does not already have a Global.asax file, create one in the root of the site. Create an event-handler method whose name follows the pattern Application_event. For example, to handle an application Error event, create a handler named Application_Error that takes an Object parameter and an EventArgs parameter. Example The following code example

However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to “Application_Error” method for handling this error like the following code. public void Application_Error(object sender, EventArgs e) { // At this point we have information about the error var ctx = HttpContext.Current; var exception = ctx.Server.GetLastError(); var errorInfo = "
Offending URL: " + ctx.Request.Url + "
Source: " + exception.Source + "
Message: " + exception.Message + "
Stack trace: " + exception.StackTrace; ctx.Response.Write(errorInfo); Server.ClearError(); } Although, this code will works fine, when normal application error occurs like error that occurs in view page. Nevertheless, it does not work when error occurs on application starting because request and response objects are always null. Next, I try to solve this question by setting default redirect in custom errors like the following code.
