You could also bind the Visibility in your stackpanel to the IsChecked property in the ToggleButton. You would need to use a custom ValueConverter. Here is one I found online:

/// 
  
/// WPF/Silverlight ValueConverter : Convert boolean to XAML Visibility
/// 
  
[ValueConversion(typeof(bool), typeof(Visibility))]
public class VisibilityConverter : IValueConverter
{
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
  {
    return (value != null && (bool)value) ? Visibility.Visible : Visibility.Collapsed;
  }

  public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
  {
    Visibility visibility = (Visibility)value;
    return (visibility == Visibility.Visible);
  }
}
