Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes asp.net application_error 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 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

How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET https://msdn.microsoft.com/en-us/library/24395wz3.aspx Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 This code example shows how to create an error handler in the Global.asax file that will catch all unhandled ASP.NET errors while processing a request — in other words, all the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site. C#VB Copy void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs // Get the exception

Error handling - handling standard errors or custom errors at page level or application level. Debugging - stepping through the program, setting break points to analyze the code In this chapter, we will discuss tracing and error handling and in this chapter, we will discuss debugging. To understand the concepts, create the following sample application. It has a label control, a dropdown list, and a link. The dropdown list loads an array list of famous quotes and the selected quote is shown in the label below. It also has a hyperlink which has points to a nonexistent link. <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="errorhandling._Default" %>

You have the Page_Error method that you add (I think) at web.config level, and the entire site gets redirected there when an error occurs. Does that mean you shouldn't use try-catch anywhere in a webforms application? (Assuming you don't want to hide any errors) asp.net exception-handling webforms share|improve this question asked Feb 17 '09 at 19:13 juan 29k40128172 add a comment| 5 Answers 5 active oldest votes up vote 12 down vote accepted Only catch the errors you can handle. If you can handle them in a manner that allows the page to continue loading then do so. Any other exception that would wreck the page should not be handled in any control or page as you would not be able to do anything anyways. Let it go to the global.asax handler and make sure you log the exception. share|improve this answer answered Feb 17 '09 at 19:17 Andrew Hare 214k40497552 add a comment| up vote 4 down vote In addition to Andrew's suggestion, make sure to update the web.config file to set CustomErrors to "On" and specify a generic error page to redirect these top level errors. Global_asax will still log the error, and then the user can see a friendly page. It will also allow you to configure a few of the standard type errors, such as 404s and 200s, plus much more. share|improve this answer answered Feb 17 '09 at 19:22 Dillie-O 20.3k1363123 add a comment| up vote 2 down vote Web Application will normally consists of UI, Business and Data access layer.Each layer must do its part regarding exception handling. Each layer must (for code re usability) check for error condition and wrap exception(after logging it) and maybe propagated to the calling layer. The UI layer should hide exception and display a friendly message. Catching all exception in UI maybe not a good idea. Exceptions if possible should be logged in Database. This will allow ease of maintainence and correction of bugs Avoid catching exc
