WPF Handedness with Popups

by

Thanks @TravisWhidden for the solution. Just implemented an improved version of it that listens to the StaticPropertyChanged event, I’ll paste it in here because it seems less of a “hack”.

private static readonly FieldInfo _menuDropAlignmentField;
static MainWindow()
{
    _menuDropAlignmentField = typeof(SystemParameters).GetField("_menuDropAlignment", BindingFlags.NonPublic | BindingFlags.Static);
    System.Diagnostics.Debug.Assert(_menuDropAlignmentField != null);

    EnsureStandardPopupAlignment();
    SystemParameters.StaticPropertyChanged += SystemParameters_StaticPropertyChanged;
}

private static void SystemParameters_StaticPropertyChanged(object sender, PropertyChangedEventArgs e)
{
    EnsureStandardPopupAlignment();
}

private static void EnsureStandardPopupAlignment()
{
    if (SystemParameters.MenuDropAlignment && _menuDropAlignmentField != null)
    {
        _menuDropAlignmentField.SetValue(null, false);
    }
}
