silverlight - window 电话 7 : Highlight Selected Listbox item

Question

我有以下 XAML(带有自定义 DataTemplate 的简单列表框)。我想弄清楚如何突出显示所选项目(可能背景颜色发生变化)。我想我需要对 Expression Blend 中的样式做一些事情，但我不太确定从哪里开始......
编辑:经过一番玩耍后，我现在有了这个(似乎什么也没做)

我的回答来自 this post帮助？

I think the easiest way would be to go via Expression Blend. Right click on your ListBox (the main control, not its items). Then go to "Edit Additional Templates....(Item Container Style)....Edit Current". Blend will then load a new page for you to modify the styling of the container. In the top left pane (where you can choose project, assets etc...) click on "States". You'll see a list of states. Modify the ones you'd like to change and hopefully that should work
