如何刪除邊距/填充併爲UWP中的分組ListView啓用全寬度？

Question

我有一個ListView與標題分組。我有一個顯示使用文本塊<TextBlock Text="{Binding Key}" />和另一個用戶控件用於結合所述列出的對象中的每個條目<local:MyListItemUserControl>報頭中的頭一個<local:MyHeaderUserControl />用戶控件。

我想沒有留下任何空白，以顯示他們全寬。 UWP中的ListView會插入令人討厭的邊距，分隔線，並且默認情況下會左對齊，並且不清楚必須在哪些可能的模板中刪除哪些屬性。

什麼是這樣做的最小化的模板？

注：我已經工作了這一點，我希望張貼的參考時，我可以，但我樂於讓別人得到的業力，如果他們那裏第一;）

這是最起碼的模板，我能找到的，但它也刪除默認樣式的焦點，選擇動畫等，這些都會在自定義的用戶控件進行處理......

<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，此模板保留默認行爲，點擊，選擇等，同時刪除邊距，並使控件的全寬...

發生這種情況的原因是，每次添加不是ListViewitem的東西時，都會自動纏繞ListViewItem，左右都會應用粗糙的10邊距。

是一個聰明的球員發揮容易髒。

而是與100線的造型xalm線打擾你可以申請您的自定義項的負-10保證金左，右的。這將強制列表項目覆蓋此列表視圖自動應用的10 px邊距。

當然，這就意味着您將首先創建一個ListViewItem的，然後這個ListViewItem的內容設置爲您的自定義項目，最後添加的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);
