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. For an ArgumentOutOfRangeException exception, the handler writes some text on the page, provides a link back to the page, logs the error, and notifies system administrators. For an InvalidOperationException exception, the handler simply transfers the exception to the Generic Error Page. For any other kind of exception, the handler does nothing, which allows your site to automatically redirect to th

Sections Configuring an Exception Handling Page Using the Developer Exception Page Configuring Status Code Pages Limitations of Exception Handling During Client-Server Interaction Server Exception Handling Startup Exception Handling ASP.NET MVC Error Handling View or download sample code Configuring an Exception Handling Page¶ You configure the pipeline handling in asp.net for each request in the Startup class's Configure() method (learn more about Application Startup). You can add a simple exception page, meant only for use during development, very easily. All that's required is to add a dependency on Microsoft.AspNetCore.Diagnostics to the project and then add one line to Configure() in Startup.cs: public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseIISPlatformHandler(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } The above code includes a check to ensure the environment is development before adding the call to UseDeveloperExceptionPage. This is a good practice, since you typically do not want to share detailed exception information about your application publicly while it is in production. Learn more about configuring environments. The sample application includes a simple mechanism for creating an exception: public static void HomePage(IApplicationBuilder app) { app.Run(async (context) => { if (context.Request.Query.ContainsKey("throw")) { throw new Exception("Exception triggered!"); } var builder = new StringBuilder(); builder.AppendLine("
Hello World!"); builder.AppendLine("- "); builder.AppendLine("
- Throw Exception"); builder.AppendLine("
- Missing Page"); builder.AppendLine(""); builder.AppendLine(""); context.Response.ContentType = "text/html"; await context.Response.WriteAs
