MVVM Pattern for Silverlight

MVVM

• Nikhil Kothari’s ViewModel Pattern in Silverlight using Behaviors This is a very good example. Also check out ViewModel Pattern extended with the Dynamic Language Runtime. Nikhil has a Silverlight.FX framework which you should try it out.
• Jonas Follesoe’s Blog This author has several blog entries and samples showing MVVM.
• Building business applications with Silverlight 2 Manish Dalal has a fairly complete sample using MVVM pattern.
• Combining different Separated Presentation Patterns
• WPF & Silverlight Line of Business UI Design Pattern Home Page

 

More patterns:

MVC

• Developing a Casual Game with Silverlight 2 This example shows a classic MVC behavior. View is responsible to create the controller. Actions from view is deligated to the controller. Model notify view on changes and view is responsible for updating itself.

MVP

• Implementing the MVP Pattern in Silverlight This example implments Passive View. The View is completely encapsulated with an interface. It is quite testable. However, even a very simple example like this one has lots of code.

• MVC# This one is similar to the previous example. It has a mini dependency injection container called TasksManager to group options together.

 

So when evaluating a pattern, it is really important to at details such as:

1. How are view and controller conntected?
2. How an user action from the view is sent to controller?
3. Who is responsible for updating the view?
