If you need to get a specific ListBoxItem at a particular index in a ListBox, you can use an ItemContainerGenerator.

The following example shows a ListBox and its items.


<ListBox Margin="10,0,0,5" Name="lb" VerticalAlignment="Top" Grid.Column="0" Grid.Row="2">
    <ListBoxItem>Item 0</ListBoxItem>
    <ListBoxItem>Item 1</ListBoxItem>
    <ListBoxItem>Item 2</ListBoxItem>
    <ListBoxItem>Item 3</ListBoxItem>
</ListBox>


The following example shows how to retrieve the item by specifying the index of the item in the ContainerFromIndex property of the ItemContainerGenerator.
