如何均匀布局一堆控件？

Question

我添加了 textbox、listpicker flyout、timepicker 和 button 控件，它们按降序排列。

每个控件都有一个 header，设置太小 无法详细说明控件的用途。

我尝试过使用网格行和列定位来布置控件，但控件在布局中的间距不均匀。此外，我无法为 header 文本大小指定字体大小。

问题：

任何人都可以为给定的控件建议一个对用户更友好的布局吗？即更大的 header 字体大小和均匀的间距。

<Grid x:Name="LayoutRoot" Background="#FF236A93">

    <Grid.ChildrenTransitions>
        <TransitionCollection>
            <EntranceThemeTransition />
        </TransitionCollection>
    </Grid.ChildrenTransitions>

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>



    <StackPanel x:Name="TitlePanel"
                Grid.Row="0"
                Margin="12,17,0,28">
        <TextBlock Style="{StaticResource SubheaderTextBlockStyle}" Text="Parking Tag Picker" />
        <TextBlock Margin="9,-7,0,0"
                   Style="{StaticResource HeaderTextBlockStyle}"
                   Text="{Binding CouncilHeaderDisplayName}" />
    </StackPanel>

    <!--  ContentPanel contains details text. Place additional content here  -->
    <Grid x:Name="ContentPanel"

您可以使用方向设置为垂直的堆栈面板，并为其中的所有元素设置一致的边距，以获得均匀间隔的元素。至于 header 字体大小，您可以为 TextBox 和 TimePicker 创建一个具有所需字体大小的自定义 HeaderTemplate。
