ItemsControl에서 AlternationIndex를 사용하여 ContentPresenter Grid.Row 인덱스를 설정할 수 없습니다.

Question

ContentPressenter를 올바른 위치에 만들려면 AlternationIndex를 사용하여 Grid.Row 값을 설정하려고합니다. 하지만 ContentPresenter의 ItemsControl.AlternationIndex를 스타일에 바인딩 할 수없는 것 같습니다. 스타일 트리거를 통해 ItemsControl.AlternationIndex에 액세스 할 수 있지만 바인딩을 통해 액세스 할 수 없습니다. ContentPresenter에 ItemsControl.AlternationIndex에 액세스하는 방법에 대한 아이디어가 있으십니까? 다음 코드는이 질문에 대한 간단한 설명입니다.

MainWindow.xaml.cs를

namespace ContentPresenterIndex 
{ 
    public class NameItem 
    { 
     public string Name { get; set; } 
     public int Age { get; set; } 
    } 

    public partial class MainWindow : Window 
    { 
     public ObservableCollection<NameItem> NameList { get; set; } 
     public MainWindow() 
     { 
      InitializeComponent(); 
      DataContext = this; 

      NameList = new ObservableCollection<NameItem> 
      { 
       new NameItem { Name = "John", Age = 20 }, 
       new NameItem { Name = "Jane", Age = 21 }, 
       new NameItem { Name = "Davie", Age = 22 }, 
       new NameItem { Name = "Robert", Age = 23 }

<ItemsControl.ItemContainerStyle> 
       <Style TargetType="{x:Type ContentPresenter}"> 
        <Setter Property="Grid.Row" Value="{Binding Path=(ItemsControl.AlternationIndex), RelativeSource={RelativeSource Self}}" /> 
       </Style> 
      </ItemsControl.ItemContainerStyle>
