Hi,

I have a problem with the binding of a custom class with custom class object within it.

I have a class Code which contain a class CodeType:
public class Code
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public CodeType CodeTypeName { get; set; }
}
public class CodeType
{
    public int Id { get; set; }
    public string Name { get; set; }
}

When I try to load the form with the following code:
public partial class Form1 : Form
    {
        private Infragistics.Win.ValueList vl = null;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            List<CodeType> ct = new List<CodeType>();
            ct.Add(new CodeType() { Id = 1, Name = "one" });
            ct.Add(new CodeType() { Id = 2, Name = "two" });

            List<Code> c = new List<Code>();
            c.Add(new Code() { ID = 1, Name = "test", Description = "test", CodeTypeName = ct[0] });
            c.Add(new Code() { ID = 2, Name = "test", Description = "test", CodeTypeName = ct[1] });
            c.Add(new Code() { ID = 3, Name = "test", Description = "test", CodeTypeName = new CodeType() { Id = 1, Name = "one" } });
            c.Add(new Code() { ID = 4, Name = "test", Description = "test", CodeTypeName = new CodeType() { Id = 2, Name = "two" } });

            vl = new Infragistics.Win.ValueList();
            vl.ValueListItems.Add(ct[0], ct[0].Name);
            vl.ValueListItems.Add(ct[1], ct[1].Name);

            this.ultraGrid1.DataSource = c;
        }

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            e.Layout.Bands[0].Columns["CodeTypeName"].ValueList = this.vl;
            e.Layout.Bands[0].Columns["CodeTypeName"].Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DropDownList;
        }
    }

I get invalid entry in the last two rows because even though the properties are the same. I believe the object itself is different because of it signature. Is there a way to prevent that from happening?

Is there a way to prevent that from happening?

I do not wish to add a ToString() or Equals() method override in my CodeType class.

Thank you
