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. http://devproconnections.com/aspnet-mvc/aspnet-mvc-tutorial-handling-errors-and-exceptions Let's find out the details and explore common practices for handling 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 con

Usually, we catch the exception and log its details to database or text,xml file and also display a user friendly message to end user in-place of error. Asp.Net MVC has some bulit-in exception filters. HandleError is the default bulit-in exception filter. Let's see how to use this filter with in your application. HandleError Attribute The HandleErrorAttribute filter works only when custom errors are enabled in the Web.config file of your application. You can enable custom errors by adding a customErrors attribute inside the node, as shown below: ... HandleError Attribute can be used to handle erro

Update – for folks who learn best visually, I’ve posted a follow-up screencast of the demo steps discussed below, as a DevNuggets video. You can view the video here. What’s an Action Filter? If you’re just getting started with ASP.NET MVC, you may have heard of something called action filters, but haven’t had the chance to use them yet. Action filters provide a convenient mechanism for attaching code to your controllers and/or action methods that implements what are referred to as cross-cutting concerns, that is, functionality that isn’t specific to one particular action method, but rather is something you’d want to re-use across multiple actions. An action filter is a .NET class that inherits from FilterAttribute or one of its subclasses, usually ActionFilterAttribute, which adds the OnActionExecuting, OnActionExecuted, OnResultExecuting, and OnResultExecuted methods, providing hooks for code to be executed both before and after the action and result are processed. Because action filters are subclasses of the System.Attribute class (via either FilterAttribute or one of its subclasses), they can be applied to your controllers and action methods using the standard .NET metadata attribute syntax: C#: 1: [MyNamedAttribute(MyParam = MyValue)] 2: public ActionResult MyActionMethod() 3: { 4: // do stuff 5: } VB: 1: _ 2: Public Function MyActionMethod() As ActionResult 3: ' do stuff 4: End Function This makes action filters an easy way to add frequently-used functionality to your controllers and action methods, without intruding into the controller code, and without unnecessary repetition. To be clear, action filters aren’t new to MVC 3, but there’s a new way to apply them in MVC 3 that I’ll discuss later on in this post. What’s in the Box? ASP.NET MVC provides several action filters out of the box: Authorize – checks to see whether the current user is logged in, and matches a provided username or role name (or names), and if not it returns a 401 status, which in turn invokes the configured authentication provider. ChildActionOnly – used to indicate that the action method may only be called as part of a parent request, to render inline markup, rather then returning a full view template. OutputCache – tells ASP.NET to cache the output of the requested action, and to serve the cached output based on the parameters provided. HandleError – provides a mechanism for mapping exceptions to specific View templates, so that you can easily
