根据Text的值更改TextBlock Background

Question

如果Text为00:00,我想更改TextBlock的Background属性.是否有一个简单的XAML解决方案？我尝试过创建一个DataTrigger,但它没有改变颜色

        <Style TargetType="TextBlock" x:Key="textBlock">
            <Style.Triggers>
                <DataTrigger Binding="{Binding}" Value="00:00">
                    <Setter Property="Background" Value="Red" />
                </DataTrigger>
            </Style.Triggers>
        </Style>

<TextBlock Text="{Binding}" Margin="3" Style="{DynamicResource textBlock}"/>

一般情况Trigger怎么样？:

<Style TargetType="TextBlock" x:Key="textBlock">
    <Style.Triggers>
        <Trigger Property="TextBlock.Text" Value="00:00">
            <Setter Property="Background" Value="Red" />
        </Trigger>
    </Style.Triggers>
</Style>
