I had a similar question which was answered here

基本上，您将 ListBox 的 AlternationCount 设置为非常高的值，并绑定到每个项目上的 AlternationIndex

Basically you set the ListBox's AlternationCount to something really high, and bind to the AlternationIndex on each item

<ListBox AlternationCount="100">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},
                                      Path=(ItemsControl.AlternationIndex)}" />
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>
