copied!<p>Because there are two different types of items, I think your best bet would be to create a custom ListBox subclass which <strong>adds a new DependencyProperty to allow you to bind and display a second list</strong>. This would also require a new default style to display the second list appropriately in the same ScrollViewer as the normal <code><ItemsPresenter/></code>.</p> <p>Here is an example of my custom ListBox to allow this:</p> <pre><code>public class MyListBox : ListBox { public MyListBox() : base() { this.DefaultStyleKey = typeof(MyListBox); } public static readonly DependencyProperty StaticItemsProperty = DependencyProperty.Register( "StaticItems", typeof(IList), typeof(MyListBox), null); public IList StaticItems { get { return (IList)GetValue(StaticItemsProperty); } set { SetValue(StaticItemsProperty, value); } } } </code></pre> <p>You would then have to copy the entire default ListBox style into your themes/generic.xaml resource dictionary and modify it to become the default style for the MyListBox control. The only thing I modified from the default style (aside from the TargetType attribute) was the content of the ScrollViewer which had the original list:</p> <pre><code><Style TargetType="custom:MyListBox">  <ScrollViewer x:Name="ScrollViewer" Background="{TemplateBinding Background}" BorderBrush="Transparent" BorderThickness="0" Padding="{TemplateBinding Padding}" TabNavigation="{TemplateBinding TabNavigation}"> <StackPanel Orientation="Vertical"> <ItemsControl ItemsSource="{TemplateBinding StaticItems}"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding}"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <ItemsPresenter/> </StackPanel> </ScrollViewer>  </Style> </code></pre> <p>As you can see I modified the ScrollViewer which normally just contained the ItemsPresenter for the ListBox and replaced it with a StackPanel containing a new ItemsControl bound to the new StaticItems DependencyProperty I added to MyListBox. I modified the DataTemplate for this ItemsControl to show a TextBox. The normal ItemsPresenter with the normal ItemsTemplate would then show up below the static list in the ScrollViewer.</p> <p>This custom ListBox can then be used in place of a normal ListBox to bind to two different lists in your ViewModel, both to your static items and your dynamic items.</p> <pre><code><custom:MyListBox x:Name="ListBox" ItemsSource="{Binding DynamicItems}" StaticItems="{Binding StaticItems}"/> </code></pre>
