获取可视化状态列表

private void Button_Click(object sender, RoutedEventArgs e)
{
    //获取CheckBox控件可视化树中的子元素数量
    int count = VisualTreeHelper.GetChildrenCount(ckbox);
    if (count > 0)
    {
        //获取CheckBox控件模板中的根元素
        FrameworkElement rootElement = VisualTreeHelper.GetChild(ckbox, 0) as FrameworkElement;
        if (rootElement != null)
        {
            //获取状态组列表
            var groups = VisualStateManager.GetVisualStateGroups(rootElement);
            foreach (VisualStateGroup group in groups)
            {
                Debug.WriteLine("状态组：" + group.Name);
                foreach (VisualState vs in group.States)
                {
                    Debug.WriteLine("\t状态：" + vs.Name);
                }
            }
        }
    }
}
