How do I get Listbox to display horizontally in code programmatically?

I have searched and searched and all I see are XAML examples. I want to do this programmatically without XAML. Here is the code:

        StackPanel stackPanel = new StackPanel();
        stackPanel.Orientation = Orientation.Horizontal;
        lstBox.Items.Add(stackPanel);
        mainGrid.Children.Add(lstBox);`

This does not work since the list remains vertical. I tried making the Listbox a child of the StackPanel and other combinations unsuccessfully.

For an horizontal panel it's better to use a WrapPanel to take benefits of the wrapping elements. Here is an example for the new year ;-)

enter image description here

XAML

<Grid>
    <ScrollViewer HorizontalAlignment="Left" Width="280" Height="99" Margin="36,159,0,0" VerticalAlignment="Top" >
        <WrapPanel x:Name="Wrappanel1" HorizontalAlignment="Left"/>
     </ScrollViewer>
</Grid>

C#

public MainWindow()
{
    InitializeComponent();

    additem(Brushes.Orange,"Hello");
    additem(Brushes.Green,"World");
    additem(Brushes.DarkOrchid,"and");
    additem(Brushes.RoyalBlue,"Happy");
    additem(Brushes.Orange, "new");
    additem(Brushes.SteelBlue, "Year");
    additem(Brushes.RoyalBlue, "for");
    additem(Brushes.Green, "2020");
    additem(Brushes.Orange, "All");
    additem(Brushes.DarkOrchid, "the");
    additem(Brushes.Orange, "best");
}

private  void additem(SolidColorBrush BackgroundColor,string information)
{
    Button but = new Button();
    but.Height = 50;
    but.Content = information;
    but.Background = BackgroundColor;
    but.FontSize = 18;
    Wrappanel1.Children.Add(but);
}

It is possible to set items panel horizontal in the following way too:

var wp = new FrameworkElementFactory(typeof(WrapPanel));
wp.SetValue(Panel.IsItemsHostProperty, true);
lstBox.ItemsPanel = new ItemsPanelTemplate(wp);         
mainGrid.Children.Add(lstBox);

The WrapPanel might be used to keep together items like buttons in a toolbar control.

If you want the elements in the ListBox to be displayed horizontally, you should set its ItemsPanel property:

FrameworkElementFactory stackPanel = new FrameworkElementFactory(typeof(StackPanel));
stackPanel.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);
lstBox.ItemsPanel = new ItemsPanelTemplate(stackPanel);
mainGrid.Children.Add(lstBox);
