I have a listbox that is created with this code:

```
    <ListBox x:Name="listBox" ItemsSource="{Binding}" ItemContainerStyle="{StaticResource Office2010SilverListBoxItemStyle}"
         SelectionChanged="listBox_SelectionChanged">
</ListBox>

```

Now I want to apply a contextmenue to each item.
How can I use my current style but with a context menue. Can i do something like a derivation from that style? Would be really great if you would know something to solve that problem... :)
