Bind current rating to ViewModel property?

[dylinmaust]

Is there any way to expose the current value of the star rating to a property on the View Model?

My workaround was to add it as a CommandParameter:

<Button Text="Submit" Command="{Binding SubmitSurveyCommand}"
            CommandParameter="{Binding Source={x:Reference starFive},Path=Rating}"/>

And react to it in the ViewModel Command:

public ICommand SubmitSurveyCommand
        {
            get
            {
                return _submitSurveyCommand ?? (_submitSurveyCommand = new Command<int>(async rating => {
                    IsBusy = true;
                    await Task.Delay(50);
                    IsBusy = false;
                }));
            }
        }
