I have a label which shows the name of the window. I want to update the colour of the label on the IsActive property of the window using styles and triggers so that all the labels inheriting this style should exhibit the same property. Please can anyone suggest me how?

I tried like this:

<Style TargetType="{x:Type Label}" x:Key="HeaderLabel">
    <Style.Triggers>
        <DataTrigger Binding="{Binding (Window.IsActive)}" Value="True">
            <Setter Property="FontSize" Value="15"/>
            <Setter Property="FontWeight" Value="Bold"/>
            <Setter Property="FontFamily" Value="Arial"/>
            <Setter Property="Foreground" Value="Black"/>
            <Setter Property="HorizontalAlignment" Value="Left"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding (Window.IsActive)}" Value="False">
            <Setter Property="FontSize" Value="15"/>
            <Setter Property="FontWeight" Value="Bold"/>
            <Setter Property="FontFamily" Value="Arial"/>
            <Setter Property="Foreground" Value="White"/>
            <Setter Property="HorizontalAlignment" Value="Left"/>
        </DataTrigger>

    </Style.Triggers>
</Style>
