Question

我有以下代码：

<HubSection x:Name="modules_section" ...>
    <DataTemplate>
        <StackPanel Orientation="Vertical">
        ..................................

如何让StackPanel获取HubSection的整个高度？

VerticalAlignment =＆＃34;拉伸＆＃34;不能完成这项工作。

我也试图通过

使用绑定

<StackPanel Height={Binding ElementName=modules_section, Path=ActualHeight}" ...>

但是hub部分的Actualheight似乎是0（我还尝试在代码隐藏中设置它并调试以查看值）。

Answer 1

<StackPanel>与其中的内容一样大，但一般来说，要使<HubSection>内的项目与该部分中的剩余空间一样高，只需设置{VerticalContentAlignment即可。 1}}在该部分，即：

<HubSection VerticalContentAlignment="Stretch">
    <DataTemplate>
        <ScrollViewer HorizontalScrollMode="..." VerticalScrollMode="...">
            <StackPanel Orientation="Vertical">
                ...

在这种情况下，我将<StackPanel>包裹在<ScrollViewer>中以应对何时有足够数据需要滚动的案例

Answer 2

如果您想使用所有高度，并且不想使用Hub.Header属性你有这个解决方案

在页面的资源中，您为HubSection编写自定义样式：

<Style x:Key="Prova" TargetType="HubSection">
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="VerticalAlignment" Value="Stretch"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
        <Setter Property="VerticalContentAlignment" Value="Stretch"/>
        <Setter Property="Padding" Value="0"/>
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="HubSection">
                    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
                        <Border.Resources>
                            <ControlTemplate x:Key="HeaderButtonTemplate" TargetType="Button">
                                <Grid Background="Transparent">
                                    <VisualStateManager.VisualStateGroups>

在你的HubSection中

然后你将有

<HubSection x:Uid="Section1Header" Style="{StaticResource Prova}">

全部

HubSection中的DataTemplate没有达到全高
