Datagrid悬停不适用于备用行颜色 - wpf

【问题描述】：

这适用于 DataGridRow..

   <Trigger Property="IsMouseOver" Value="true">
        <Setter Property="Background" Value="{StaticResource RolloverBrush}" />
        <Setter Property="Foreground" Value="#000" />
   </Trigger>

但是当我添加这些时，鼠标悬停样式不起作用..

<Trigger Property="ItemsControl.AlternationIndex" Value="0">
    <Setter Property="Background" Value="{StaticResource LightRowBrush0}" />
</Trigger>
<Trigger Property="ItemsControl.AlternationIndex" Value="1">
    <Setter Property="Background" Value="{StaticResource LightRowBrush1}" />
</Trigger>

【解决方案1】：

样式的顺序很重要。

在其他触发器起作用之前应用交替触发器。

    <Style.Triggers>
        <Trigger Property="ItemsControl.AlternationIndex" Value="0">
            <Setter Property="Background" Value="{StaticResource LightRowBrush0}" />
        </Trigger>
        <Trigger Property="ItemsControl.AlternationIndex" Value="1">
            <Setter Property="Background" Value="{StaticResource LightRowBrush1}" />
        </Trigger>
        <Trigger Property="IsMouseOver" Value="true">
            <Setter Property="Background" Value="{StaticResource RolloverBrush}" />
            <Setter Property="Foreground" Value="#000" />
        </Trigger>
        <Trigger Property="IsSelected" Value="true">
            <Setter Property="Background" Value="{StaticResource SelectedBrush}" />
            <Setter Property="Foreground" Value="#000" />
        </Trigger>
    </Style.Triggers>

但这行得通，<Style TargetType="DataGrid" BasedOn="{StaticResource {x:Type DataGrid}}"> <Setter Property="AlternatingRowBackground" Value="#FF282828"/> </Style>
