Model-View-Controller with WPF

March 30, 2009 Leave a comment

With WPF, it is very simple follow the MVC pattern where a CLR object or XML is acting as your Model, and you want to present the data from the Model in a View, which is built in XAML by binding WPF controls to elements in the Model. What happens when we want to make changes to the data in the Model, such as updating some properties of that object? Your user is interacting with the View, so you need something in between the View and the Model, which is your Controller.

The most common approach to updating the data is to write event handlers in the code behind for your XAML file (your View). However, this means that your Controller logic is tightly coupled with your View…you can’t easily reuse it in another View. If you implement your Controller logic as a WPF ICommand, you can keep the logic in a different class and use it declaratively from any XAML file.
