UWP 应用程序中的滚动查看器无法正常工作

Question

我有一个横向模式的页面，在代码中设置了下一行：

DisplayInformation.AutoRotationPreferences = DisplayOrientations.LandscapeFlipped | DisplayOrientations.Landscape;

全屏模式代码如下：

Windows.UI.ViewManagement.ApplicationView view = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView();
view.TryEnterFullScreenMode();

在我的滚动查看器中，我想从 syncfusion 包中包含一些动态创建的图表。
我认为这是问题所在，但过了一会儿，我尝试在网格中创建一些行只是文本块，所以我可以尝试滚动查看器，但它也不起作用。

这是我的所有页面内容（页面和 page.resources 内容除外）：

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid.RowDefinitions>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition Height="auto"/>
        <RowDefinition />
    </Grid.RowDefinitions>
    <StackPanel Background="{StaticResource AccentBrush}" Grid.Row="0" Margin="0,0,0,10">
        <TextBlock Name="Statistic_name" HorizontalAlignment="Center" FontSize="23" Text="Estadísticas"/>

                <TextBlock Grid.Row="11">Hola 11</TextBlock>
                <TextBlock Grid.Row="12">Hola 12</TextBlock>
                <TextBlock Grid.Row="13">Hola 13</TextBlock>
                <TextBlock Grid.Row="14">Hola 14</TextBlock>
                <TextBlock Grid.Row="15">Hola 15</TextBlock>
                <TextBlock Grid.Row="16">Hola 16</TextBlock>
                <TextBlock Grid.Row="17">Hola 17</TextBlock>
            </Grid>
        </ScrollViewer>
    </StackPanel>
</Grid>

谁能告诉我错误在哪里？

我尝试修改了很多代码，结果总是一样。我认为这是因为内容是在 C# 部分动态创建的，但在尝试使用文本块后，情况似乎并非如此。

将包含滚动查看器的 Grid.Row=2 的 <RowDefinition Height="auto"/> 更改为 <RowDefinition Height="*"/> 或指定滚动查看器的最小高度。

也删除 Stackpanel，只需使用 Scrollviewer
