在UWP中保持ListView.HeaderTemplate可见/静态/粘性 [英] Keep ListView.HeaderTemplate visible/static/sticky in UWP

问题描述

我需要始终保持ListView的HeaderTemplate可见，但是我不知道要设置什么，或者不知道要更改ListView模板的哪一部分来做到这一点.

I need to keep the HeaderTemplate of a ListView visible at all times, but I don't know what to set, or what part of the ListView's template to change to do that.

我当前拥有的内容会导致ListView的标题在向下滚动项目时从顶部滚动到顶部.

What I currently have causes the header of the ListView to scroll off the top when scrolling down through items.

即使滚动浏览ListView的项目，如何保持ListView的标题行"?

How can I keep the header "row" of the ListView visible even when scrolling through the ListView's items??

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>

将此样式应用于您的ListView，您将获得静态标头

Apply this style to your ListView and you will have static header

    <Style TargetType="ListView" x:Key="FixedHeaderListViewStyle">
