我有一个userControl，它是一个里面有按钮的列表框。记录更新后，列表重新加载。我有一个转换器检查按钮是否可见。但是，即使按钮的内容不可见，按钮的边框仍然可见。有人会告诉我该怎么做吗？提前谢谢。

有我的用户控件：

有一些代码可以反弹itemsSoruce：

 //update the image and status to the list
    private void UpdateUI()
    {

        foreach (QueueItem a in ar.cmsQueue)
        {
            if (Convert.ToInt32(a.callNumber) == currentCall.id)
            {
                a.status = UPSTATUS; //status:responded;
                var location = (from c in ar.cmsQueue orderby c.callNumber select c);
                Dispatcher.BeginInvoke(new Action(() => lst.lst.ItemsSource = location));


            }
        }

    }

您可以将以下（在样式中）设置为未显示的内容（例如Transparent）

 BorderBrush="#FFF19D47"

或将BorderThickness设置为0
