wpf datagrid alternate row coloring

Finally, this is what I ended up with for generically setting alternate row colors.

<Style TargetType="{x:Type DataGrid}">
    <Setter Property="Background" Value="#FFF" />
    <Setter Property="AlternationCount" Value="2" />
</Style>

 <Style TargetType="{x:Type DataGridRow}">
    <Style.Triggers>
        <Trigger Property="ItemsControl.AlternationIndex" Value="0">
            <Setter Property="Background" Value="#CCC"></Setter>
        </Trigger>
        <Trigger Property="ItemsControl.AlternationIndex" Value="1">
            <Setter Property="Background" Value="#EEE"></Setter>
        </Trigger>
    </Style.Triggers>
</Style>
