C# 列表框与问题重叠后的列表框

我有一个列表框新闻和列表框评论，我试图显示：

列表框新闻

列表框注释

但是没有成功。 我有，这是xaml：

您需要在scrollViewer中包装两个列表框，并禁用列表框的滚动：

<ScrollViewer VerticalScrollBarVisibility="Enabled">
    <StackPanel>
        <ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" />
        <ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" />
    </StackPanel>
</ScrollViewer>
