How to get relative source of item in ItemTemplate

I have a ListBox with specified ItemTemplate. And the ItemTemplate contain itself ListView and I want to display in that ListView a collection, which is actually a property of the item of the ListBox.

Could you show me how to do Binding. I'm thinking about RelativeSource thing, but I don't know what corre开发者_JS百科ct syntax would look like...

Nevermind, I found the answer.

it should be like this:

ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor,
                                     AncestorType={x:Type ListBoxItem}},Path=DataContext.YourCollectionProperty}
