Now let's add some sample data to the ListBox.
  1. public class Person  
  2.     {  
  3.         public string Name { get; set; }  
  4.         public int Age { get; set; }  
  5.         public string Country { get; set; }  
  6.     }  
  7. ObservableCollection<Person> myList;  
  8.         public Window1()  
  9.         {  
  10.             InitializeComponent();  
  11.             myList = new ObservableCollection<Person>()  
  12.             {  
  13.                 new Person{ Name="Name 1", Age=24, Country="India"},  
  14.                 new Person{ Name="Name 2", Age=24, Country="India"},  
  15.                 new Person{ Name="Name 3", Age=24, Country="India"},  
  16.                 new Person{ Name="Name 4", Age=24, Country="India"},  
  17.                 new Person{ Name="Name 5", Age=24, Country="India"},  
  18.                 new Person{ Name="Name 6", Age=24, Country="India"},  
  19.                 new Person{ Name="Name 7", Age=24, Country="India"},  
  20.                 new Person{ Name="Name 8", Age=24, Country="India"},  
  21.                 new Person{ Name="Name 9", Age=24, Country="India"},  
  22.                 new Person{ Name="Name 10", Age=24, Country="India"},  
  23.                 new Person{ Name="Name 11", Age=24, Country="India"},  
  24.                 new Person{ Name="Name 12", Age=24, Country="India"},  
  25.                 new Person{ Name="Name 13", Age=24, Country="India"},  
  26.                 new Person{ Name="Name 14", Age=24, Country="India"},  
  27.                 new Person{ Name="Name 15", Age=24, Country="India"},  
  28.                 new Person{ Name="Name 16", Age=24, Country="India"},  
  29.                 new Person{ Name="Name 17", Age=24, Country="India"},  
  30.                 new Person{ Name="Name 18", Age=24, Country="India"},  
  31.                 new Person{ Name="Name 19", Age=24, Country="India"},  
  32.                 new Person{ Name="Name 20", Age=24, Country="India"},  
  33.                 new Person{ Name="Name 21", Age=24, Country="India"},  
  34.                 new Person{ Name="Name 22", Age=24, Country="India"},  
  35.             };  
  36.             lbPersonList.ItemsSource = myList;  
  37.         }  
Now Bind the Property "Name" to the ListBox, so that we can see the Names.
  1. <ListBox x:Name="lbPersonList" Margin="19,17,162,25">  
  2.             <ListBox.ItemTemplate>  
  3.                 <DataTemplate>  
  4.                     <TextBlock Text="{Binding Name}"/>  
  5.                 </DataTemplate>  
  6.             </ListBox.ItemTemplate>  
  7. </ListBox>

If you see from the above wecannot differentiate with each row, I mean to say the Row Background color is all same white.
 
Now we would add a style to the ListBoxItem.
  1. <Window.Resources>  
  2.         <Style  TargetType="{x:Type ListBoxItem}">  
  3.             <Style.Triggers>  
  4.                 <Trigger Property="ItemsControl.AlternationIndex" Value="0">  
  5.                     <Setter Property="Background" Value="#19f39611"></Setter>  
  6.                 </Trigger>  
  7.                 <Trigger Property="ItemsControl.AlternationIndex" Value="1">  
  8.                     <Setter Property="Background" Value="#19000000"></Setter>  
  9.                 </Trigger>  
  10.             </Style.Triggers>  
  11.         </Style>  
  12. </Window.Resources>  
  13.   
  14. <ListBox x:Name="lbPersonList" Margin="19,17,162,25" AlternationCount="2">  
  15.             <ListBox.ItemTemplate>  
  16.                 <DataTemplate>  
  17.                     <TextBlock Text="{Binding Name}"/>  
  18.                 </DataTemplate>  
  19.             </ListBox.ItemTemplate>  
  20. </ListBox>  
Now run the application.

Yes, we got alternate row colors.
 
We can have value more than 2 as AlternationCount and add that many colors and you will see the Repeatation of colors after the AlternationCount.
