How to Create Scrollbar for a ListBox in C#

I am using silverlight and coding in c# and i have to create a scrollbar on a list displayed.

Currently the list is displayed without scrollbar but it should contain one scrollbar as well.

My code to display the List is:

ListBox lines = new ListBox(); 
ScrollViewer scrollViewer = new ScrollViewer();            
scrollViewer.VerticalScrollBarVisibility = ScrollBarVisibility.Visible;
lines.ItemsSource = param.Component.Attributes.Items;
Grid.SetColumn(lines, 1);
Grid.SetRow(lines, LoopCount);
childGrid.Children.Add(lines);

lines.SelectedIndex = 0;
lines.SelectedItem = param.Component.Attributes.Items;
lines.SelectionChanged += new SelectionChangedEventHandler(List_SelectionChanged);
lines.SelectedIndex = lines.Items.Count - 1;

"lines" variable contains my ListBox and i tried to achieve it throught scrollViewer but i dont know how to proceed further. (Please note that i have to create selection changed event on selecting the items on GUI displayed on button click) so the code for scrollbar must not influence that procedure. And i have to code in c# only not in xaml. Thanks in advance for the help.

When you are puttig items Inside ScrollViewer You need to set the Content of ScrollViewer to ListBox,

change your code like below,

//Create ScrollViewer which is a child of Grid
var scroll = new ScrollViewer();
//add to the grid
childGrid.Children.Add(scroll);
//create lisbox and set it to the content of scrollviewer which is a Child of ScrollViewer
var listBox = new ListBox();
scroll.Content = listBox;
