获取所有子ListView的高度

Question

所以我有一个带有 StackPanel 的 ScrollView 。在StackPanel内部，我有三个ListViews ，具有不同的List<object>-sources。

我想要实现的是禁用ListViews上的滚动，只在同一个ScrollView中滚动所有滚动。

当我对滚动视图的高度进行硬编码时，我得到了一些滚动的东西，但如果我不这样做，它只会在我释放手指后快速重新开始。如何才能达到高度？

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>

Answer 1

所以我发现了这个：

外面的StackPanel一切都毁了一切。我将其更改为Grid并制作了ScrollView *。现在一切正常
