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 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 wo

The framework publishes exceptions to a database if able. I've done a good amount of research on exception handling but I'm having a bit of trouble c# event handler understanding how I'm supposed to handle exceptions which occur inside event handlers (i.e. a timer.elapsed or an async callback). Should each event handler have a try catch block?

Also, event handlers are expected to execute quickly so avoid performing expensive IO or database operations inside the event handler itself. Furthermore, you can have a property like Error to indicate to the subscribers of the event that an error has occurred (in case of an async call).
