xaml - 在 UWP 中保持 ListView.HeaderTemplate 可见/静态/粘性

Question

我需要保留 HeaderTemplate的 ListView始终可见，但我不知道该设置什么，或者 ListView 的哪个部分的模板来改变来做到这一点。

我目前拥有的导致 ListView 的标题向下滚动项目时从顶部滚动。

如何保留 ListView 的标题“行”即使滚动浏览 ListView 也可见的元素？？

这是我的 XAML:

<ListView x:Name="permitResults"
          Grid.Row="1"
          AutomationProperties.AutomationId="PermitResults"
          AutomationProperties.Name="Permit Search Results"
          ItemsSource="{Binding Source={StaticResource ResultsSource}}" 
          ItemClick="permitResults_ItemClick"
          SelectionMode="None"
          TabIndex="1"
          Padding="0"
          Margin="0"
          BorderThickness="0"
          IsSwipeEnabled="True"
          IsItemClickEnabled="True"
          ScrollViewer.VerticalScrollBarVisibility="Auto" >
    <ListView.HeaderTemplate>
        <DataTemplate>
            <Grid Margin="0,0,0,0" Width="1366" Height="Auto" HorizontalAlignment="Left">
                <Grid.Resources>

将此样式应用于您的 ListView你将有静态标题

    <Style TargetType="ListView" x:Key="FixedHeaderListViewStyle">
        <Setter Property="IsTabStop" Value="False" />
        <Setter Property="TabNavigation" Value="Once" />
