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 App_Code folder) GenericErrorPage.aspx https://msdn.microsoft.com/en-us/library/bb397417.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 Visual Studio. In a production environment, th

You can also download a sample I’ve built that shows how to implement this here.Some Background asp net error Discussion on Error Handling and ASP.NET Custom Error Pages:ASP.NET and .NET support a rich error-handling architecture that provides a flexible way to catch/handle errors at multiple levels within an application. Specifically, you can catch and handle a runtime exception with a class, within a page, or on the global application level using the Application_Error event handler within the Global.asax class. If a runtime exception isn’t handled/cancelled by one of these mechanisms, then ASP.NET’s Custom Error Page feature will kick-in, and an error page will be sent back to the browser accessing the application.ASP.NET’s Custom Error Page feature can be used to configure a “friendly error page” to be displayed to end-users in place of the standard “server error occurred” message sent back by ASP.NET. For example, the below web.config file section will cause remote users visiting the site to be redirected to a “friendlyErrorPage.htm” file anytime a runtime error occurs (note: HTTP 500 stat

Sometimes we use a custom validator control instead of other controls to implement our custom logic to validate user input.We use the ErrorMessage property to display the error message. Assume you get a requirement to display the error message dynamically. Then it will not help to implement it directly (we need to implement it in code behind, not in the aspx
