Bool to visibility converter class

    public class BoolToVisibilityConverter : IValueConverter
        {
            public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
            {
                return (bool)value ? Visibility.Visible : Visibility.Hidden;
            }

            public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
            {
                throw new NotImplementedException();
            }
        }

Xaml Changes mentioned below to show use of visibility converter class. A group box is used here to show the visibility. on change of radio button selection group box will be visible/hidden.

In ViewModel use invokepropertychange than only you will get the visibility changes on your xaml.

private Boolean isCustomerDetailChecked = false;
    public Boolean IsCustomerDetailChecked
    {
        get
        {
            return isCustomerDetailChecked;
        }
        set
        {
            isCustomerDetailChecked = value;
            InvokePropertyChanged("IsCustomerDetailChecked");
        }
    }
