获取所有子 ListView 的高度

Question

所以我有一个带有 StackPanel 的 ScrollView。在 StackPanel 中，我有 三个 ListViews 与不同的 List<object>-sources。

我想要实现的是禁用 ListViews 上的滚动，并且只在同一个 ScrollView 中滚动它们。

当我硬编码滚动视图的高度时，我得到的东西滚动有点好，但如果我不这样做，它只会在我松开手指后重新开始。我怎样才能获得高度？

当前 XAML：

<Style x:Key="ListViewHeaderDisableScroll" TargetType="ListView">
                <Setter Property="ScrollViewer.VerticalScrollMode" Value="Disabled" />
                <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Disabled" />
                <Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="False" />
            </Style>

        <Page
        x:Class="TestApp.SecondaryView.PatientDetailView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        </Grid>

所以我发现了这个：

一切都在外面的 StackPanel 确实毁了一切。我将其更改为 Grid 并制作了 ScrollView *.现在一切正常
