how can I enable scrollbars on the WPF Datagrid?

Question

When I run the following Northwind WPF Toolkit Datagrid code from this article, I get a datagrid, but there are no scrollbars and hence the user can only see part of the datagrid. I am using the newest version March 2009.

What do I need to specify so that the WPF Datagrid has scrollbars?

I tried putting the datagrid in a ScrollViewer but that didn't help.

XAML:

<Window x:Class="TestDataGrid566.Window1"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit"     Title="Window1" Height="600" Width="800">     <StackPanel>         <toolkit:DataGrid x:Name="TheDataGrid" AutoGenerateColumns="True"/>     </StackPanel> </Window> 

code-behind:

using System.Linq; using System.Windows; using TestDataGrid566.Model;  namespace TestDataGrid566 {     public partial class Window1 : Window     {         public Window1()         {             InitializeComponent();              NorthwindDataContext db = new NorthwindDataContext();             var customers = from c in db.Customers                             select c;             TheDataGrid.ItemsSource = customers;         }     } }

Put the DataGrid in a Grid, DockPanel, ContentControl or directly in the Window. A vertically-oriented StackPanel will give its children whatever vertical space they ask for - even if that means it is rendered out of view.
