CommandBar.Content AppBarButton标签位置右

这是我的代码：

       <CommandBar DefaultLabelPosition="Right" IsOpen="True">
            <CommandBar.Content>
                <AppBarButton Icon="Account" Label="Test 1"></AppBarButton>
            </CommandBar.Content>
            <AppBarButton Icon="Accept" Label="Test 2"/>
        </CommandBar>

这就是我得到的结果： enter image description here

那么我现在如何触发标签在右边？ DefaultLabelPosition不会影响内容值。

我想在WPF或WinForms中创建一个工具栏。

这里有几点需要注意。

1）DefaultLabelPosition可用于定位周年纪念更新的应用。因此，如果您想将此功能用于定位以前版本的应用，则无法使用。

2）无论上述情况如何，CommandBar.Content本身都是AppBarButton的独立主持人。

我怎样才能使这个工作？

您可以使用默认AppBarButton模板创建样式模板，并根据需要设计ContentRoot。

以下是我之前玩过时改变的网格。

<Grid x:Name="ContentRoot" MinHeight="{ThemeResource AppBarThemeMinHeight}">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>
    <ContentPresenter x:Name="Content" AutomationProperties.AccessibilityView="Raw" Content="{TemplateBinding Icon}" Foreground="{TemplateBinding Foreground}" HorizontalAlignment="Stretch" Height="20" VerticalAlignment="Center"/>
    <TextBlock x:Name="TextLabel" Foreground="{TemplateBinding Foreground}" FontSize="12" FontFamily="{TemplateBinding FontFamily}" Margin="5,0" Grid.Row="0" Grid.Column="1" TextAlignment="Center" TextWrapping="Wrap" Text="{TemplateBinding Label}" VerticalAlignment="Center"/>
</Grid>

此外，Style还有VisualState Compact，它隐藏了AppBar Close上的标签文本，因此请对此进行评论

然后将此样式指定给按钮。

<Page.BottomAppBar>
    <CommandBar IsOpen="True">
        <CommandBar.Content>
            <AppBarButton Icon="Account" Label="Test 1" Style="{StaticResource RightAlignAppBarButton}"/>
        </CommandBar.Content>
        <AppBarButton Icon="Accept" Label="Accept" Style="{StaticResource RightAlignAppBarButton}" />
    </CommandBar>
</Page.BottomAppBar>

这是输出

以下是完整的参考样式。
