问题
I have the following code:
<HubSection x:Name="modules_section" ...>
<DataTemplate>
<StackPanel Orientation="Vertical">
..................................
How can I get the StackPanel to take the full height of the HubSection?
VerticalAlignment="Stretch" doesn't do the job.
I also tried to use binding via
<StackPanel Height={Binding ElementName=modules_section, Path=ActualHeight}" ...>
but the Actualheight of the hub section seems to be 0 (I also tried to set it in code-behind and debugged to see the value).
回答1:
A <StackPanel> is as large as the content within it, but in general, to make the items within a <HubSection> as tall as the remainingspace in the section it is as simple as setting the VerticalContentAlignment on the section, i.e:
<HubSection VerticalContentAlignment="Stretch">
<DataTemplate>
<ScrollViewer HorizontalScrollMode="..." VerticalScrollMode="...">
<StackPanel Orientation="Vertical">
...
In this case, I'm wrapping my <StackPanel> in a <ScrollViewer> to cope with when the case with when there is enough data to need to scroll

If you want to use all the height and you don't want to user the Hub.Header property you have this solution
In the resources of the page you write a Custom Style for the HubSection:
<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">

<!--<Rectangle x:Name="HubHeaderPlaceholder" Grid.Row="0"/>-->
<!--<Button x:Name="HeaderButton" ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" FontWeight="{ThemeResource HubSectionHeaderThemeFontWeight}" FontSize="{ThemeResource HubSectionHeaderThemeFontSize}" Margin="{ThemeResource HubSectionHeaderThemeMargin}" Grid.Row="1" Template="{StaticResource HeaderButtonTemplate}"/>-->
<ContentPresenter x:Name="ContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Grid.Row="2"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
in your HubSection then you will have
<HubSection x:Uid="Section1Header" Style="{StaticResource Prova}">
That's all
