Databind value array to list datatemplate

I have a datatemplate for listbox:

<DataTemplate>
    <Rectangle Width="10" Height="{Binding ???}" Fill="Black" HorizontalAlignment="Center"/>
</DataTemplate>

The ItemSource of the开发者_如何学Python list is set to int[] array. What should I specify in Binding ??? to make the binding path take the concrete value?

Thanks.

Have you tried just {Binding}?

This will take the item itself.
