Custom data binding with object hierarchy

Question

Hello. I'm trying to bind my own objects to a win control. The problem is that when i create a datasource, it only exposes the base class fields. Let me try to explain:

public class Entities : IList<Entity>

public class Entity
{
  public int databaseId;
  public int quantity;
}

public class Component : Entity
{
  public string code;
}

In datasource creation wizard i select Entities class. It successfully recognizes databaseId and quantity fields, but doesn't see the code field. I want to have a control, that displays databaseId, quantity and, if it's a Component, code. Is this possible? Thank you.
