当alternate reocrd为true时，Xamdatagrid设置所选背景颜色

Question

当备用行为真时，我当前面临将背景颜色设置为黄色的问题

我有一个网格，其中几列背景设置为不同的颜色。我已经设置了高光交替行是真的。当选择记录时，我也设置了黄色背景。

若要在选择备用记录时保持黄色背景，请将CellValuePresenter背景设置为透明。像这样的东西应该能起作用。

<Style x:Key="CellBackgroundStyle" TargetType="{x:Type igDP:CellValuePresenter}" >
    <Style.Triggers>
        <DataTrigger Binding="{Binding Path=IsMouseOver, RelativeSource={RelativeSource AncestorType={x:Type igDP:DataRecordCellArea}}}" Value="True">
            <Setter Property="Background" Value="Transparent"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={RelativeSource AncestorType={x:Type igDP:DataRecordCellArea}}}" Value="True">
            <Setter Property="Background" Value="Transparent"/>
        </DataTrigger>
        <DataTrigger Binding="{Binding Path=IsActive, RelativeSource={RelativeSource AncestorType={x:Type igDP:DataRecordCellArea}}}" Value="True">
            <Setter Property="Background" Value="Transparent"/>
        </DataTrigger>
    </Style.Triggers>
</Style>
