The question makes no sense. If you added, a list box in code behind, you can add an event handler as well. This is not related to XAML. So, what's the problem? (Especially after you mentioned AddHandler yourself...)

I Suppose you wanted this, your question is not very clear.

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            CreateStackPanel();
        }
        private void CreateStackPanel()
        {
            // Create a StackPanel
            StackPanel MyStackPanel = new StackPanel();
            MyStackPanel.Orientation = Orientation.Horizontal;

            //Add Listbox and add Items
            ListBox lstBox = new ListBox();
            lstBox.Items.Add("item1");
            lstBox.Items.Add("item2");
            lstBox.Items.Add("item3");
            lstBox.Items.Add("item4");
            lstBox.Items.Add("item5");
            //Adding Handler to Listbox
            lstBox.SelectionChanged += new SelectionChangedEventHandler(OnSelectionChanged);
            MyStackPanel.Children.Add(lstBox);

            // Display StackPanel
            RootWindow.Content = MyStackPanel;
        }
       
        void OnSelectionChanged(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("You have selected " + ((System.Windows.Controls.ListBox)(sender)).SelectedItems[0].ToString() + ".");   
        }
