相关疑难解决方法(0)

我试过这种方法..没有运气..

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

有没有办法获得行索引？我甚至试过了

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