如何删除UWP中的上下文菜单项之间的空间

Question

我在上下文菜单中有项目，项目之间有更多空间。我尝试了很多方式来创建物品容器，将边距减小到0，填充为零。没有什么works.May任何人都可以帮助我解决这个问题。

您还没有提供任何代码，但您可以创建自定义弹出的右键菜单。 This GitHub sample可以帮助你。如果短期内，您可以根据需要添加到页面资源弹出和改变风格：

<Page.Resources> 
    <MenuFlyout x:Key="SampleContextMenu"> 
     <MenuFlyoutItem Text="Open" Tag="&#xE1A5;" /> 
     <MenuFlyoutItem Text="Print" Tag="&#xE2F6;" /> 
     <MenuFlyoutItem Text="Delete" Tag="&#xE10A;" /> 
     <MenuFlyoutSubItem Text="Other"> 
      <MenuFlyoutItem Text="Sort by" /> 
      <MenuFlyoutItem Text="Name" /> 
      <MenuFlyoutItem Text="Date" /> 
      <MenuFlyoutItem Text="Size" /> 
     </MenuFlyoutSubItem> 
    </MenuFlyout> 
</Page.Resources> 

而且里面CS：

 protected override void OnRightTapped(RightTappedRoutedEventArgs e) 
    { 
     ShowContextMenu(null, e.GetPosition(null)); 
     e.Handled = true; 

     base.OnRightTapped(e); 
    } 

    private void ShowContextMenu(UIElement target, Point offset) 
    { 
     var MyFlyout = this.Resources["SampleContextMenu"] as MenuFlyout; 
     MyFlyout.ShowAt(target, offset); 
    }
