很难在列表视图（WPF）中创建自动排序

Question

目标：
最新添加的数据应该在列表视图（WPF）的第一行。排序部分基于列日期。

问题：
不知道如何在添加数据后在列表视图中进行自动排序。

请记住，我不使用语法itemsource，列表和绑定源。

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 
/// </summary> 
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); 
    } 




}

Answer 1

努力创造这样的事情（从MSDN略有修改）：

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(); 
} 

并使用它如下：

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