Aspx Error Handling
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. This code example shows a handler for the Error event in an ASP.NET Web page. This handler catches all exceptions that are not already handled within Try/Catch blocks in the page. After you handle an error, you must clear it by calling the ClearError method of the Server object (HttpServerUtility class). Example This handler filters for specific kinds of exceptions.

Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example https://msdn.microsoft.com/en-us/library/bb397417.aspx 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 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 .ht

There are enormous articles written earlier for this topic. I have tried writing this article for beginners explaining these concepts in simple language and step-by-step.This is a very basic article for beginners that show exception handling and error handling techniques in ASP.NET.Where there are codes, the chances for exceptions / error always exist so it is very important for developers when developing web applications to understand the errors and implement the error handling techniques to avoid breaking pages or providinig unhandled errors to end uses.What Exceptions are

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" %>
