DataGridTemplateColumn行悬停文本框前景

Question

我有一个DataGridTemplateColumn，里面有一个文本框。当我将鼠标悬停在该行上时，除文本框外，所有其他前景都会变为白色。当鼠标悬停在行上时，我可以将哪种样式应用于文本框以使其前景更改以匹配其他文本块/字体？

示例XAML

<DataGridTemplateColumn>
  <DataGridTemplateColumn.CellTemplate>
    <TextBox Text="Test 123" />
    <TextBlock Text="Test 123" />
  </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

<Style TargetType="{x:Type DataGridRow}">
    <Setter Property="Background"
            Value="Transparent" />
    <Setter Property="BorderBrush"
            Value="{x:Null}" />
    <Setter Property="Foreground"
            Value="{StaticResource BlackBrush}" />
    <Style.Triggers>
        <Trigger Property="IsSelected"
                 Value="True">
            <Setter Property="Background"
                    Value="Transparent" />
            <Setter Property="BorderBrush"
                    Value="{x:Null}" />
            <Setter Property="Foreground"

                    Value="{StaticResource WhiteBrush}" />

<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="Padding"
            Value="5, 10" />
    <Setter Property="IsTabStop"
            Value="False" />

                    <ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
                </Border>

您需要为Style定义一个额外的TextBox：

<Style TargetType="TextBox">
    <Style.Triggers>
        <DataTrigger Binding="{Binding IsMouseOver, RelativeSource={RelativeSource AncestorType=DataGridRow}}" Value="True">
            <Setter Property="Foreground" Value="White" />
        </DataTrigger>
    </Style.Triggers>
</Style>
