Cant Sort ObservableCollection List by any Item

Question

i want sort my ObservableCollection list but i cant find how.

I want sort;

ObservableCollection < CariHesaplarPickerItems > _pickerlistItemsSource = new ObservableCollection < CariHesaplarPickerItems > ();

by ID.

My main code:

public List < string > pickerListItems = new List < string > {...};

ObservableCollection < CariHesaplarPickerItems > _pickerlistItemsSource = new ObservableCollection < CariHesaplarPickerItems > ();

private async Task GetAllData() 
{
  ...

  var resCariGrup = await client.ExecuteAsync(request, Method.Post);
  var dataCariGrup = JsonConvert.DeserializeObject < RootCariGrup > (resCariGrup.Content);

  _pickerlistItemsSource.Clear();
  pickerListItems.Clear();
  pickerListItems.Add("Hepsi");

  for (int i = 0; i < dataCariGrup.data.Count(); i++) 
  {
    ...
  }
  pickerCariListe.ItemsSource = pickerListItems;

  ...
}

List items:

public class CariHesaplarPickerItems
{
    public int ID { get; set; }
    public string grupAd { get; set; }
    public string kullaniciAd { get; set; }
    public string subeAd { get; set; }
}

I want sort this items

You can do something like below to order your collection based on ID

_pickerlistItemsSource.OrderBy(var=> var.ID)

This will return an ordered list of objects

this is not solved my problem – BySuspect Jul 28 '22 at 07:55
`OrderBy` returns a new `IEnumerable` so you'd want `var sortedList = _pickerlistItemsSource.OrderBy(var=> var.ID)` or something to that effect – lee-m Jul 28 '22 at 07:58
`_pickerlistItemsSource = new ObservableCollection(_pickerlistItemsSource.OrderBy(i => i.ID));` this solved my problem thx – BySuspect Jul 28 '22 at 08:10
@BySuspect: Getting the idea of sorting your collection should be good enough to take it further based of your needs. – Maddy Jul 28 '22 at 08:27
