This documentation is archived and is not being maintained. Filtering in ASP.NET MVC In ASP.NET MVC, controllers define action methods that usually have a one-to-one relationship with possible user interactions, such as clicking a link or submitting a form. For example, when the user clicks a link, a request is routed to the designated controller, and the corresponding action method is called.Sometimes you want to perform logic either before an action method is called or after an action method runs. To support this, ASP.NET MVC provides filters. Filters are custom classes that provide both a declarative and programmatic means to add pre-action and post-action behavior to controller action methods.A Visual Studio project with source code is available to acc

Dino Esposito | Dev Pro EMAIL Tweet Comments 0 Advertisement RELATED: "Using Data Annotations for ASP.NET MVC 3 Input Validation" and mvc error handling best practice "Exploring the Razor Syntax in ASP.NET MVC 3" In ASP.NET MVC, error handling can be split in two parts: handling errors and exceptions that occur within the code and handling exceptions at the framework https://msdn.microsoft.com/en-us/library/gg416513(VS.98).aspx level. You can easily deal with the first type of exceptions; however, you have to intervene in various places and use different tools to neutralize the impact of route exceptions and HTTP errors. In the end, you gain total control over runtime exceptions by writing error handlers within controllers and at least a global exception handler in global.asax. Let's find out the details and explore common practices for handling http://devproconnections.com/aspnet-mvc/aspnet-mvc-tutorial-handling-errors-and-exceptions exceptions in ASP.NET MVC. Catching Exceptions in Controllers In controllers you write plain code, and in plain code you typically catch exceptions by using try/catch blocks. This approach gives you the most flexibility but at the cost of adding some noise to the code. Having a bunch of try/catch blocks scattered through a single method, though effective, makes reading the code a bit more difficult. The point here is not to question the importance of exception handling but simply to consider whether there's a better way of achieving the same results using easier-to-read code. Conveniently in this regard, Microsoft offers us the OnException overridable method and the HandleError filter attribute. Both methods -- and one method doesn't exclude the other -- allow us to trap any exceptions raised around the controller code without having to write any explicit try/catch blocks. In particular, the OnException method that's defined on the base controller class behaves like a predefined global exception handler that simply wraps up any controller method you may have. To explain this in more detail, in ASP.NET MVC the execution of each controller method is governed by an action invoker. This is a system component responsible for executing a controller method, capturing any response it

Summary http://www.prideparrot.com/blog/archive/2012/5/exception_handling_in_asp_net_mvc Introduction Exception handling is a serious matter in any application, http://stackoverflow.com/questions/13606643/error-while-adding-exception-filter-in-mvc-3 whether it's web or desktop. Implementing a proper exception handling is important in any application. In most cases once we catch the exception we have to log the exception details to database or text file and show a friendly message to the in mvc user. In ASP.NET applications, error handling is done mostly in two ways: at local level using try-catch blocks and at global level using application events. ASP.NET MVC comes with some built-in support for exception handling through exception filters. The HandleError is the default built-in exception filter. Unfortunately, the HandleError filter not gives a action filters in complete answer to the exception handling problem and that makes us to still rely on the Application_Error event. In this article, we will learn about the HandleError filter and discuss about the different exception handling mechanisms that will fit to an MVC application. HandleError Attribute Exception filters The exception filters are attributes that can be applied over an action or a controller or even at a global level. When you apply the filter at the global level then it will handle the exceptions raised by all the actions of all the controllers. The exception filters not only catches the exceptions that are raised by the actions but also the ones that are raised by the action filters that are applied over the actions. All the exception filters implements the IExceptionFilter interface. Listing 1. shows the definition of this interface. The IExceptionFilter contains a single method called OnException which will be called whenever an exception occurs. The Exception

Join them; it only takes a minute: Sign up Error While adding Exception Filter in MVC 3 up vote 1 down vote favorite I am trying to create custom exceptions for my mvc 3(razor) application. But its not working properly. Following is the code I've written for custom exception class. using System; using System.Web.Mvc; namespace TestApp.Helpers { public class CustomExceptionAttribute : FilterAttribute, IExceptionFilter { public void OnException(ExceptionContext filterContext) { if (!filterContext.ExceptionHandled && filterContext.Exception is Exception) { //filterContext.Result = new RedirectResult("/shared/Error.html"); filterContext.Result = new ViewResult { ViewName = "Error" }; filterContext.ExceptionHandled = true; } } } } Below is the code in controller: using System; using System.Collections.Generic; using System.Data; using System.Data.Entity; using System.Linq; using System.Web; using System.Web.Mvc; using System.Text; using TestApp.Domain; using TestApp.Helpers; namespace TestApp.Controllers { [CustomException] public class MyController : Controller { private TestAppEntities db = new TestAppEntities(); public ActionResult Create(int id) { // Throwing exception intentionally int a = 1; int b = 0; int c = a / b; //This is another method which is working fine. return View(CreateData(id, null)); } } } And below is the code in 'Error.cshtml' @model System.Web.Mvc.HandleErrorInfo @{ ViewBag.Title = "Error"; }

Sorry, an error occurred while processing your request.

There was a @Model.Exception.GetType().Name while rendering @Model.ControllerName's @Model.ActionName action.

The exception message is: <@Model.Exception.Message>

Stack trace:

@Model.Exception.StackTrace
