Are there events for before a controller is run?

Question

I know there are events for before/after a action is fired.

Is there anything higher up in the stack like before a controller is called?

outside of the controller, higher up in the stack just before the controller is called. — Blankman, Jun 02 '10 at 20:57
If you are trying to figure out which controller is going to be instantiated at run-time, a controllerfactory would help. Hard to say what you mean without an example of what you are trying to accomplish. — Jab, Jun 03 '10 at 14:11

There's no such notion as running a controller. Controllers are not run. They are classes which are instantiated and actions (methods) are invoked on them.

You could decorate your controller action with a custom [ActionFilter] attribute in which you could override the OnActionExecuting which will be called before the controller action is invoked. This technique also allows you a better separation of concerns.

ASP.Net MVC still runs through the HttpApplication pipeline, so you can still handle any of the events from BeginRequest through to PreRequestHandlerExecute by adding handlers to Global.asax.

Many application lifecycle events can be handled in the Global.asax file.

Please see the following SO question which explain the lifecycle in ASP.NET MVC.

What is the 'page lifecycle' of an ASP.NET MVC page, compared to ASP.NET WebForms?
