Eu preciso manter oHeaderTemplate de umListView visível o tempo todo, mas não sei o que definir ou que parte doListViewmodelo para mudar para fazer isso.

O que tenho atualmente faz com que o cabeçalho doListView rolar para cima e para baixo ao rolar pelos itens.

Como posso manter o cabeçalho "linha" doListView visível mesmo ao rolar pelaListViewitens ??

Aqui está o meu 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>
                        <Style TargetType="TextBlock" BasedOn="{StaticResource SearchGridResultsHeaderTextBlock}">
                            <Setter Property="HorizontalAlignment" Value="Left"></Setter>
                        </Style>
                    </Grid.Resources>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"></RowDefinition>
