UWP -使用Stackpanel内容定制ListBoxItemStyle

Question

在UWP-XAML中，我正在为ListBoxItem的造型概念而挣扎。

我想要实现的是ListBox的样式，它的项目由两个TextBlocks的StackPanel组成，例如，当PressedSelected时，两个TextBlocks的前景发生了不同的变化。

使用下面的ListBox示例，我只能在标准ListBoxItemStyle中对ContentPresenter进行样式设置，并且两个TextBlocks一起更改。

<ListBox>
    <ListBox.ItemTemplate>
        <DataTemplate x:DataType="local:DataSet">
            <StackPanel>
                <TextBlock x:Name="number" Text="{x:Bind Number}"/>
                <TextBlock x:Name="name" Text="{x:Bind Name}"/>
            </StackPanel>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

您必须编辑ItemContainer的样式。将ContentPresenter替换为堆栈面板及其内容。但是，我使用了绑定而不是x:Bind。似乎不可能在样式内使用x:Bind

<Style TargetType="ListBoxItem" x:Key="ListViewStyle">
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}" />
            <Setter Property="TabNavigation" Value="Local"/>
            <Setter Property="IsHoldingEnabled" Value="True"/>
            <Setter Property="Padding" Value="12,0,12,0"/>
            <Setter Property="HorizontalContentAlignment" Value="Left"/>
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="MinWidth" Value="{ThemeResource ListViewItemMinWidth}"/>
            <Setter Property="MinHeight" Value="{ThemeResource ListViewItemMinHeight}"/>
            <Setter Property="UseSystemFocusVisuals" Value="True" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem">
                        <Grid x:Name="ContentBorder"
              Background="{TemplateBinding Background}"
              BorderBrush="{TemplateBinding BorderBrush}"
              BorderThickness="{TemplateBinding BorderThickness}">
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="Normal">

                                    <VisualState x:Name="PointerOver">
