具有水平堆栈面板的 Listview 不滚动 Windows 10 通用应用程序

Question

我正在尝试构建一个 4 列列表视图来显示 Windows 通用应用程序中的一些数据。我有以下 Listview，但尽管有数据可供滚动，但列表视图并未垂直滚动。我不确定我做错了什么。任何指针或帮助表示赞赏..

Answer 1

您的问题是包含titlebar 和SplitView 的StackPanel。 StackPanel 内的内容不限于任何空间，它会永远延伸。在您的情况下，这意味着 SplitView 以及其中的 ListView 将永远延伸。不受限制ListView 不认为它需要滚动。

解决方法是改用Grid 和Rows。我会将Grid RowDefinitions 添加到您的body Grid 中，并在第0 行添加titlebar，在第1 行添加SplitView，然后删除body Grid 中的StackPanel。这将使您的滚动工作。解释您的代码，行定义如下所示

    <Grid x:Name="body">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
        </Grid.RowDefinitions>

        <Grid x:Name="titlebar" Grid.Row="0">
        </Grid>

        <SplitView x:Name="MySplitView" Grid.Row="1">
        </SplitView>

    </Grid>
