ListBoxItem ControlTemplete.Triggers WPF

Question

我正在对ListBox控件应用ItemContainerStyle。在我的ListBoxItem样式中，我有几个触发器，其中包含应用于ListBoxItem (IsSelected，IsMouseOver)的当前状态的情节提要动画。

直到我选择了一个ListBoxItem之后，之前选择的ListBoxItem的IsMouseOver故事板动画才会被触发。

我看不出问题出在哪里，所以我希望有人能帮我解决这个问题。

干杯

下面是我使用的代码

<Style x:Key="ListBoxFeedItemStyle" TargetType="{x:Type ListBoxItem}">
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
    <Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
    <Setter Property="Padding" Value="2,0,0,0"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListBoxItem}">
                <Border x:Name="Bd" Background="{TemplateBinding Background}" Margin="5" SnapsToDevicePixels="true">
                    <Grid Name="Grid" Height="Auto" Margin="5">
                        <TextBlock Margin="10" Text="{Binding Path=Name}" FontSize="14" TextTrimming="CharacterEllipsis" />
                    </Grid>

检查触发器的顺序。看一看Multiple storyboards on one property

看看尤里的answer.May吧，这就是你要找的。
