Question

Goal:
Latest added data should be on the first line in the listview (WPF). 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 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"));


    }




}

public partial class ControlTower : Window

    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);
    }

Answer 1

Try to create something like this (slightly modified from MSDN):

private void Sort(string sortBy, ListSortDirection direction)
{
    // The MSDN version pass ItemsSource property
    ICollectionView dataView =
      CollectionViewSource.GetDefaultView(lv.Items);

    dataView.SortDescriptions.Clear();
    SortDescription sd = new SortDescription(sortBy, direction);
    dataView.SortDescriptions.Add(sd);
    dataView.Refresh();
}

And use it as follows:

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