WPF MVVM Navigate between Views on button click

[admin]

I am trying to create a WPF application and for Navigation I am using the example I found at

Now, I need to navigate from one UserControl to another on button click.

Can somebody guide me how to achieve this with MVVM? Or if I should look at using some framework for Navigation.
