在WPF ListBoxItems中为鼠标悬停和选择使用序列图像板动画

我有一个WPF应用程序,它有一个列表框,我正在尝试应用一些鼠标悬停效果。当我使用简单的 Setter s来更改mouseover/selection上的背景色,但我认为如果在不同状态之间设置动画效果会更好,所以我切换了 Storyboard s、 这一切都很好地开始工作(mouseover动画输入和输出,选择动画输入和输出),但一旦选定的东西,然后成为deselect,它将永远不会再做mouseover效果。

下面是显示问题的最小代码示例:

      <ListItem/>
      <ListItem/>
      <ListItem/>
      <ListItem/>
    </ListBox>

</Window>

IsSelected 退出情节提要。

有什么想法吗?
