我有一个Silverlight应用程序，我正在尝试设置样式。当控件获得焦点时，此样式会在不同的颜色边框中淡入淡出。当控件没有焦点时，我希望它恢复原来的样子。我的风格目前有两个问题：
有人可以看看我的模板并帮我确定我做错了什么吗？我已将代码包含在哪里，您应该可以复制并粘贴它。

答案 0 :(得分：0)
你的myfield风格有几个问题。首先，您要更改处于单独VisualStateGroup中的Visual状态中的相同属性。这可能导致不稳定的行为（如果打开模板，Blend会显示此警告）。
其次，您正在控制聚焦元素的边框颜色以及主边框。只需选一个就可以了。
尝试这种风格，而不是修复这些问题。我认为这就是你要找的东西：
