The ASP.Net framework

In ASP.Net, the patterns for the view component and the controller component are well-defined. Only the pattern for the model component is left to be designed by the developer as per the specific application requirements.

View: The files that handle the responsibilities associated with the view component are ASPX and ASCX. In this design, the view object typically inherits from the controller object.

Controller: The responsibilities of the controller component are split among two components. The generation and passing of events is done by the framework and, to be more specific, is done by the Page and Control classes. The event handling is taken care of by the code-behind class.

Model: ASP.NET does not necessarily require a model. It is left to the choice of the developer whether to create a model class, or to forgo it. In case a model is not used, the event handlers in the controller can be used to perform any calculations and also ensure data persistence.
