Model-view-presenter (MVP) is a variation on MVC that is designed to fit more easily with stateful GUI platforms such as Windows Forms or ASP.NET Web Forms. This is a worthwhile attempt to get the best aspects of the smart UI pattern without the problems it usually brings.
In this pattern, the presenter has the same responsibilities as an MVC controller, but it also takes a more direct relationship to a stateful view, directly managing the values displayed in the UI components according to the user’s inputs and actions. There are two implementations of this pattern:
-
The passive view implementation, in which the view contains no logic. The container is for UI controls that are directly manipulated by the presenter.
-
The supervising controller implementation, in which the view may be responsible for some elements of presentation logic, such as data binding, and has been given a reference to a data source from the domain models.
The difference between these two approaches relates to how intelligent the view is. Either way, the presenter is decoupled from the GUI framework, which makes the presenter logic simpler and suitable for unit testing.
