DataTrigger with Value Binding

Why this doesn't work?

 <Style x:Key="ItemContStyle" TargetType="{x:Type Lis开发者_StackOverflow社区tViewItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Path=Asset}" 
          Value="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}},
                       Path=CurrentAsset}">
                <Setter Property="Background" Value="Red" />
            </DataTrigger>
  </Style.Triggers>

Because DataTrigger.Value is not a dependency property.

Used StyleSelector instead...
