I'm trying to set a global style for all the listboxes in my application. Below is the xaml code that i've used. Here i've tried to trigger out an animation but it doesn't work. I just want an animation on the selected item. Any help?

<Style TargetType="{x:Type ListView}">
    <Style.Setters>
        <Setter Property="BorderThickness" Value="5" />
        <Setter Property="FontSize" Value="16" />
        <Setter Property="FontFamily" Value="Arial" />
        <Setter Property="ItemTemplate">
            <Setter.Value>
                <DataTemplate x:Name="ListViewItemTemplate">
                    <TextBlock Text="{Binding}" Padding="0,0,5,5"/>
                </DataTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate>
                    <ControlTemplate.Triggers>
                        <EventTrigger RoutedEvent="ListViewItemBase.Selected">
                            <BeginStoryboard>
                                <Storyboard TargetProperty="Color">
                                    <ColorAnimation To="#FFFF0000" Duration="0:0:1" AutoReverse="true" />
                                </Storyboard>
                            </BeginStoryboard>
                        </EventTrigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
