How To Handle Application Error In Global.asax In Mvc
This documentation is archived and is not being maintained. Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors page level error handling in asp.net example section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name extensions to ASP.NET. Note In the example, the mode attribute is set to "On" so that you can error messages when you run the example in Visual Studio. In a production environment, this setting would normally be "RemoteOnly". ASP.NET then renders error pages to external users. If a request is made on the server computer (localhost), ASP.NET ren

I have https://msdn.microsoft.com/en-us/library/bb397417.aspx 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 http://stackoverflow.com/questions/7875947/global-error-handling-in-asp-net 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 12.7k2791183 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 45.5k85385 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 t
