You would need to set the DataContext property of your Window (say it is Window1) that contains the ListBox control, inside the Window1.xaml.cs class's constructor like this:

public Window1()
{
    MyViewModel vm = new MyViewModel();

    this.DataContext = vm;
}

Next step is to set the ItemsSource property of your ListBox control (inside XAML) to the Items property that you have made available inside your ViewModel class:

<ListBox ItemsSource="{Binding Path=Items}">
    <!--Other XAML-->
</ListBox>

Additionally, you should also implement the INotifyPropertyChanged interface for your MyListBoxItem class which is explained here in MSDN. This is because implementing MVVM pattern in your WPF app. requires that you implement change notifications for oneway or twoway databindings to work (see this to learn more on DataBinding).

Here is a more detailed explanation of MVVM on MSDN.
