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 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 I

or Application level Posted By hershey on Oct 10, 2013 | 0 comments Download PDFWelcome to CodeSpread! A regular query of a developer as which is the best way to handle errors? at Page level or Application level. Best answer is why to chose one over the other? Lets have both. We will try some sample for Page level Error Handling and Application level Error Handling. How to Handle errors at Page level? To catch errors, the best way available is Try/Catch block on code file. public void Calculate() { try { //Do some Calculation } catch(Exception ex) { //Log Exception } } In the above sample, an exception can be corrected at the same time it occurred. We have another way where a page-level error handler can be created to catch any exceptions that are not caught within Try/Catch block. privatevoid Page_Error(object sender, EventArgs e) { // Get last error Exception ex = Server.GetLastError(); if (ex is InvalidOperationException) { // Handle or Log exceptions } } Note: --latest from codespread-- Tip : Code Structure C#Importance of Software MaintenanceSoftware Testing Life Cycle (STLC)App_Offline Updates in Webdeploy V3 and Visual Studio 2013OLAP : On-line Analytical Processing What is an API and What good is it?prevnext If the handler can't resolve the exception,control is transferred to the error handler in the Global.asax file and is handled at application level. Still the exception remains unresolved, Web.config file can be configured to redirect the site to redirect to the generic page specified. Refer Custom Errors. How to Handle errors at Application level? To Handle errors at Application level,create an error handler in the Global.asax file. void Application_Error(object sender, EventArgs e) { // Get the last error. Exception ex = Server.GetLastError(); // Handle HTTP errors if (ex.GetType() == typeof(HttpException)) { //Handler Implementation //Redirect to Error page Server.Transfer("Error.aspx"); } // Clear the error from the server Server.ClearError(); } Global.asax file cannot be used to show error information so server.transfer is used to maintain current context and transfer it to another webpage like an error page. Here, the error information can be shown. Note: Avoid showing compromising information about the Web site directly to the user.
