如何删除边距/填充并为UWP中的分组ListView启用全宽度？

我有一个ListView与标题分组。我有一个显示使用文本块<TextBlock Text="{Binding Key}" />和另一个用户控件用于结合所述列出的对象中的每个条目<local:MyListItemUserControl>报头中的头一个<local:MyHeaderUserControl />用户控件。如何删除边距/填充并为UWP中的分组ListView启用全宽度？

我想没有留下任何空白，以显示他们全宽。 UWP中的ListView会插入令人讨厌的边距，分隔线，并且默认情况下会左对齐，并且不清楚必须在哪些可能的模板中删除哪些属性。

什么是这样做的最小化的模板？

注：我已经工作了这一点，我希望张贴的参考时，我可以，但我乐于让别人得到的业力，如果他们那里第一;）

也许[this]（https://stackoverflow.com/a/38151627/6843321）可以提供帮助。 –

谢谢，这是解决方案的一部分，但组头模板更复杂，并且默认的GroupStyles插入硬编码边距的加载，更重要的是在Windows 8中使用的旧ContainerStyle在UWP中被弃用，在更新我的代码时使我失望 – Brendan

这是最起码的模板，我能找到的，但它也删除默认样式的焦点，选择动画等，这些都会在自定义的用户控件进行处理......

<ListView 
    ItemsSource="{Binding Source={StaticResource collectionViewSource}}" 
    > 
    <ListView.ItemContainerStyle> 
     <Style TargetType="ListViewItem"> 
      <Setter Property="Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="ListViewItem"> 
         <local:MyListItemUserControl /> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style> 
    </ListView.ItemContainerStyle> 
    <ListView.GroupStyle> 
     <GroupStyle> 
      <GroupStyle.HeaderContainerStyle> 
       <Style TargetType="ListViewHeaderItem"> 
        <Setter Property="Margin" Value="0" /> 
        <Setter Property="Padding" Value="0" /> 
        <Setter Property="Template"> 
         <Setter.Value> 
          <ControlTemplate TargetType="ListViewHeaderItem"> 
           <local:MyHeaderUserControl /> 
          </ControlTemplate> 
         </Setter.Value> 
        </Setter> 
       </Style> 
      </GroupStyle.HeaderContainerStyle> 
     </GroupStyle> 
    </ListView.GroupStyle> 
</ListView>

或者，此模板保留默认行为，点击，选择等，同时删除边距，并使控件的全宽...

发生这种情况的原因是，每次添加不是ListViewitem的东西时，都会自动缠绕ListViewItem，左右都会应用粗糙的10边距。

是一个聪明的球员发挥容易脏。

而是与100线的造型xalm线打扰你可以申请您的自定义项的负-10保证金左，右的。这将强制列表项目覆盖此列表视图自动应用的10 px边距。

当然，这就意味着您将首先创建一个ListViewItem的，然后这个ListViewItem的内容设置为您的自定义项目，最后添加的ListViewItem到你的ListView。

 MyListItemUserControl item = new MyListItemUserControl(); 
     item.Height = 45; 
     item.Margin = new Thickness(-10, 4, -10, 4); 
     item.HorizontalAlignment = HorizontalAlignment.Stretch; 

     ListViewItem ListItem = new ListViewItem(); 
     ListItem.HorizontalAlignment = 
     HorizontalAlignment.Stretch; 
     ListItem.HorizontalContentAlignment = HorizontalAlignment.Stretch; 
     ListItem.Content =item; 
     LIST.Items.Add(ListItem);
