Question

我有以下XAML（带有自定义DataTemplate的简单列表框）。我正在试图弄清楚如何突出显示所选项目（可能是背景颜色变化）。我想我需要在Expression Blend中使用Styles做一些事情，但我不太清楚从哪里开始...... 编辑：经过一段时间的游戏，我现在有了这个（似乎没有做任何事情）

this post的回答是否有帮助？

我认为最简单的方法就是去通过Expression Blend。右键单击你的ListBox（主要控件，不是它的项目）。然后转到“编辑附加模板....（项目容器样式）....编辑当前“。然后Blend将加载一个新页面你要修改的造型容器。在左上方的窗格中（其中你可以选择项目，资产等...）点击“States”。你会看到一个清单国家。修改你想要的改变，希望这应该工作
