Is MVVM suitable for WP7 app development?

Question

I am developing an app using Windows Phone 7. I have used MVVM for WPF app development before but was wondering if MVVM is suitable for WP7 app development too. If not can you please suggest some architectures\frameworks to refer to use in WP7.

If I use MVVM, how do we navigate from one page to another and set DataContext of the page to a ViewModel?

Thanks.

Answer 1

Absolutely!

There are tons of resources online that talk about MVVM use in Windows Phone Dev .. simply search.

Two prominent MVVM frameworks in use are:

• MVVM Light: http://galasoft.ch/mvvm/
• Ultralight MVVM: http://ultralightmvvm.codeplex.com/

Have fun!

Data context can be set in the constructor of the .xaml page:

PageViewModel viewModel = new PageViewModel();
this.DataContext = viewModel;

Also, from what I know, interface related actions can be done in the view so for navigation you could simply subscribe to some event in the view and then:

PhoneApplicationFrame frame = (PhoneApplicationFrame)Application.Current.RootVisual;
frame.Navigate(new Uri("/Views/NewPage.xaml", UriKind.Relative));
