Answer 1

<ListBox>
  <ListBox.ItemTemplate>
   <Grid>
     <TextBlock Text="{Binding Path=Name}" Grid.Row=0/>
        <ComoboBox Name="test" 
           DataContent="{Binding RelativeSource={RelativeSource AncestorType=ListBox}}"                 
           ItemsSource="{Binding}"
        DisplayMemberPath="Country"
        SelectedValuePath="Country_ID">
   </Grid>

Now your combocbox is always have the same itemssource as the parent listbox.
