HTML5，CSS3参考[关闭](HTML5, CSS3 reference [closed])

 经过多次努力，我终于通过电子邮件发送了组件Owl（开发出更好的listview控件的公司）支持团队并得到了快速回复。 我希望它可能对某人有所帮助，所以我引用了Libor Tinka先生（ComponentOwl.com的首席开发人员）的答案： 
 
 “不支持这个框，但可以使用自定义绘图擦除不需要的网格线。只需将BetterListView子类化并添加OnDrawGroup方法覆盖：

    base.OnDrawGroup(eventArgs);
}

    base.OnDrawGroup(eventArgs);
}
