So you could write a custom action filter on the server which catches exception and transforms them into JSON response: public class MyErrorHandlerAttribute : FilterAttribute, IExceptionFilter { public void OnException(ExceptionContex

[HttpPost] public ActionResult UpdateUser(UserInformation model){ // Instead of throwing exception throw new InvalidOperationException("Something went wrong"); // I need something like return ExecutionError("Error Message"); // which should be received as an error to my // $.ajax at client side... } Problems http://stackoverflow.com/questions/8702103/how-to-report-error-to-ajax-without-throwing-exception-in-mvc-controller with Exceptions We have to log exceptions in case of device or network errors like SQL Connectivity errors. These messages are like validation messages for users, we dont want to log. Throwing exceptions also floods Event Viewer. I need some easy way to report some custom http status to my $.ajax call so that it should result an error at client side, but I do not want to throw an error. UPDATE I cannot change client script because it becomes inconsistent with other data source. So far, HttpStatusCodeResult should work but it's IIS that is causing the problem here. No matter what error message I set, tried all answers, still I receive default message only. c# ajax asp.net-mvc controller share|improve this question edited Jan 3 '12 at 8:00 asked Jan 2 '12 at 14:41 Akash Kava 24.6k1379128 add a comment| 8 Answers 8 active oldest votes up vote 26 down vote accepted This is where HTTP status codes come into play. With Ajax you will be able to handle them accordingly. [HttpPost] public ActionResult UpdateUser(UserInformation model){ if (!UserIsAuthorized()) return new HttpStatusCodeResult(401, "Custom Error Message 1"); // Unauthorized if (!model.IsValid) return new HttpStatusCodeRes
basics of jquery ajax and ASP MVC. - So you know how to make ajax call, but you want to learn how to handle http://codedreaming.com/asp-mvc-handle-ajax-errors-properly/ ajax errors properly? What to do if there is unauthorized ajax call? Then go on with reading. I'd like to show you simple Add Entity demo with proper ajax error handling: 1. Controller action [HttpPost] public ActionResult Add(Entity entity) { var valid = Validate(entity); if(!valid) { return new HttpStatusCodeResult(400, "You can't add this entity."); } /*Business logic*/ return this.Add(entity); //return error handling PartialView with list of Entities } 2. Javascript function add() { var isvalid = $("#form").valid(); if (!isvalid) { return; } $.ajax({ url: addUrl, data: $("#form").serialize(), type: "POST", dataType: "html" }) .success(function (result, status) { $("#entities").html(result); /*additional logic*/ }) .error(function (xhr, status) { if (xhr.status == 401) { window.location = unauthorizedUrl; //redirect to unauthorized url } if (xhr.statusText == null || xhr.statusText == ajax error handling "") { showError("There was an error while adding Entity. Please try again."); //show default message } else { showError(xhr.statusText); //show message from response } }); } We have two callbacks success: - When everything goes fine show updated list of entities. error: This is a part that is more interesting. Something happen in application and we want to handle the error. Lets take it from bottom: 1. Status is not 401 and there is a statusText in response (we have send message in response) - showError(xhr.statusText); //show message from response 2. Status is not 401 but there is not statusText (we haven't send any message in response) - showError("There was an error while adding Entity. Please try again."); //show default message 3. status is 401. - window.location = unauthorizedUrl; //redirect to unauthorized url However this will not work, without little hack. 401 means unauthorized request. MVC framework will automatically look for this in your app and will redirect you(302=redirect) to your unauthorized error page. And then will return this page (200 = success). So that means you will end up in success callback an
