tavPositions.FillBy_All(vPositions);

this.XamComboEditor_WACChairmanPosition.ItemsProvider.ItemsSource = vPositions.DefaultView;

Hello,

Just tested it with the NorthWind database and still works fine. I am using v8.2

Here is the code:

DataSet1 ds = new DataSet1();
DataSet1TableAdapters.CustomersTableAdapter cusAd = new WpfApplication3.DataSet1TableAdapters.CustomersTableAdapter();
            cusAd.Fill(ds.Customers);

            xamComboEditor1.DisplayMemberPath = ds.Customers.CityColumn.ToString();
            xamComboEditor1.ItemsSource = ds.Customers;

As it works fine with me, you can give me a sample project to take a look.

Ok,

I will explore this scenario as well and post a follow-up here.

it seems this occure when binded to DataTable 

Hello,

It works fine with me. The data is shown properly. Here is the code that I used.

public List<Person> people = new List<Person>();
        public Window1()
        {
            InitializeComponent();
            for (int i = 0; i < 30; i++)
            {
                Person p = new Person();
                p.Name = "Person "+ i.ToString();
                people.Add(p);
            }
            xamComboEditor1.ItemsSource = people;
            xamComboEditor1.DisplayMemberPath = "Name";
        }

        public class Person
        {
            public string Name { get; set; }
        }

Or am I missing something?

Alex.
