                        <Style.Triggers>
                            <DataTrigger Binding="{Binding DataItem.ResultText, Converter={StaticResource IsNotNullOrEmptyConverter}}" Value="True">

为什么你不做这样简单的事情

<DataTrigger.EnterActions>
    <BeginStoryboard>
        <Storyboard>
            <ColorAnimation Storyboard.TargetProperty="Background.Color" To="Red" 
                    RepeatBehavior="3x" Duration="0:0:1" AutoReverse="True"/>
            <ColorAnimation Storyboard.TargetProperty="Background.Color" To="Red" 
                    Duration="0:0:1" BeginTime="0:0:4"/>
        </Storyboard>
    </BeginStoryboard>
</DataTrigger.EnterActions>
<DataTrigger.ExitActions>
    <BeginStoryboard>
        <Storyboard>
            <ColorAnimation Storyboard.TargetProperty="Background.Color" To="White" />
            <ColorAnimation Storyboard.TargetProperty="Background.Color" To="White"/>
        </Storyboard>
    </BeginStoryboard>
</DataTrigger.ExitActions>
