How to: Handle Page-Level Errors asp net mvc error handling Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 If possible, you should handle errors in Try/Catch blocks within your code, because a problem is more easily corrected where it occurs. If the user can help correct a problem, the page needs to return to the same place so the user has a context for understanding what to do. A page-level handler returns you to the page, but there is no longer anything on the page because instances of controls are not created. To provide the user any information, you must specifically write it to the page. You would probably use a page-level error handler to log unhandled errors or to take the user to a page that can display helpful information.

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.

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" %>
