Difficult to Create an automatical sorting in listview (WPF)

Question

Goal:
Latest added data should be on the first line of in listview. The sorting part is based on column date.

Problem:
Dont't know how to make a automatical sorting in the listview after adding a data.

Please remember that I don't use syntax itemsource, List<XXXXXX> and Binding source.

public partial class FlightForm : Window
{

    public delegate void TakeOffHandler(object source, TakeOffEventArgs e);
    public delegate void ChangeHandler(object source, ChangeRouteEventArgs e);

    public event TakeOffHandler TakeOffEvent;
    public event ChangeHandler ChangeEvent;


    public FlightForm()
    {
        InitializeComponent();

        Title = "Flight ";

        cmbStatus.Visibility = Visibility.Hidden;
        btnLand.Visibility = Visibility.Hidden;
    }



    private void btnStart_Click(object sender, RoutedEventArgs e)
    {

        cmbStatus.Visibility = Visibility.Visible;
        btnLand.Visibility = Visibility.Visible;
        btnStart.Visibility = Visibility.Hidden;

        TakeOffEvent(this, new TakeOffEventArgs("a", "b", DateTime.Now.ToString()));
        ChangeEvent(this, new ChangeRouteEventArgs("aa", "bb", "cc"));


    }




}

/// <summary>
/// Interaction logic for MainWindow.xaml

public partial class ControlTower : Window
{
    public ControlTower()
    {
        InitializeComponent();
    }

    private FlightForm myFlightForm;


    private void btnSendNextAirplane_Click(object sender, RoutedEventArgs e)
    {
        myFlightForm = new FlightForm();

        myFlightForm.TakeOffEvent += new FlightForm.TakeOffHandler(PrintOutTakeOff);
        myFlightForm.ChangeEvent += new FlightForm.ChangeHandler(PrintOutChange);
        myFlightForm.Show();

    }




    public void PrintOutTakeOff(object source, TakeOffEventArgs e)
    {

        lstDisplay.Items.Add(new { FlightCode = e.FlightCode, Status = e.Status, Time = e.Time });

    }


    public void PrintOutChange(object source, ChangeRouteEventArgs e)
    {
        string test = e.FlightCode + e.Status + e.Time;

        MessageBox.Show(test);
    }




}
