Answer 1

Take a look at the concept of Filters in ASP.NET MVC and also to the following 4 methods in the controller base class: OnActionExecuting, OnResultExecuting, OnAuthorization, and OnException.

Update On a second though I just realize that you might be looking for methods at the Model level and I answered from the Controller level. Unfortunately from what I understand that ASP.NET MVC does not provide as much at the Model level as Ruby On Rails does.
