Binding ViewModel to multiple windows

Question

I\'m re-writing my windows forms project that does scoring for sheep shearing events (don\'t ask, its a huge sport in New Zealand) from vbnet to wpf c# and have struck a problem

Answer 1

I suspect that each window is creating its own instance of the ViewModel. You could try the following:

public MainWindow()
{
    InitializeComponent();

    SheepViewModel svm = new SheepViewModel();
    this.DataContext = svm;

    ScoreScreen SW = new ScoreScreen();
    SW.DataContext = svm;
    SW.Show();        
}
