xaml - wpf datagrid alternate row coloring

Question

I have tried this method.. without luck..

 <Style TargetType="{x:Type DataGridRow}">
  <Style.Triggers>
      <Trigger Property="ItemsControl.AlternationIndex" Value="0">
          <Setter Property="Foreground" Value="Red" />
     </Trigger>
  </Style.Triggers>
</Style>

Is there a way to get the row Index? I have even tried

<DataTrigger Binding="{Binding AlternationIndex}" Value="0">
    <Setter Property="Foreground" Value="Green"></Setter>
</DataTrigger>

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>
