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 https://msdn.microsoft.com/en-us/library/bb397417.aspx 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 IIS to map file-name extensions to ASP.NET. Note In the example, the mode attribute is set to "On" so that you can error messages when you run the example in V

Managing Exceptions with the Debugger Visual Studio 2015 Other Versions Visual Studio error handling and 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 Visual Studio .NET 2003 An exception is an indication of an error state that occurs while a program is being executed. You can and should provide handlers that respond to the most important exceptions, but it’s important to know how to set up the debugger to break for the exceptions you want to see.When an exception occurs, the debugger writes an exception message to the Output window. It may break execution in the following cases:when an exception is thrown and is not handled.when the debugger is set to break execution immediately when an exception is thrown, before any handler is invoked.if you have set Just My Code, and the debugger is set to break on any exception that is not handled in user code.Note ASP.NET has a top-level exception handler that shows error pages in a browser. It does not break execution unless Just My Code is turned on. For an example, see Setting the debugger to continue on user-unhandled exceptions below.Note In a Visual Basic application, the debugger manages all errors as exceptions, even if you use On Error–style error handlers.Managing Exceptions with the Exception Settings WindowYou can us

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 areGuys, the MSDN says that an exception is an error condition or unexpected behavior encountered by a
