VerticalScrollBar for a listbox inside an Expander - WPF

I'm working on a WPF application. I have a listbox inside an Expander, and what I want to do is for the list box to have a vertical scroll bar. Here is my code:

<Expander Grid.Row="1" Header="More Details" >
    <ListBox ScrollViewer.VerticalScrollBarVisibility="Visible" 
             Height="20"
             ItemsSource="{Binding Path=DetailsItemsSource, Mode=TwoWay}" 
             ItemTemplate="{Binding Path=DetailsTemplate, Mode=TwoWay}">
    </ListBox>
</Expander>

I can see a scrollbar area in the listbox , but no scrollbar itself (even when there are unseen items). Thanks!

Change the layout to remove the Expander and use Grid and see if that helps.Another solution will be you need to set the Height property of ScrollViewer.Something like this,

<Expander Header="expander1" Width="150" HorizontalAlignment="Left">
                <ScrollViewer Height="75">
                    <ListBox>

                    </ListBox>
                </ScrollViewer>
</Expander>
