Populate a datagridview

I have a List of "Person" object:

public class Person
{
   public Int32 Id { get; set; }
   public String Name { get; set; }
   public Document oDocument  { get; set; }
}

And also there is Document class.

public class Document
{
   public String Type { get; set; }
   public String Code { get; set; }
}

I need to populate a DataGridView with that list showing some just two columns:Name(Person) and DocumentCode (Document)

I used this code, but I dont get what I want.

  dgvPersona.DataSource = list;

try this:

  public class Person
        {
            public Int32 Id { get; set; }
            public String Name { get; set; }
            public Document oDocument { get; set; }
        }
        public class Document
        {
            public String Type { get; set; }
            public String Code { get; set; }
        }

     List<Person> list = new List<Person>();
     dgvPersona.DataSource= list.Select(data => new { data.Name, data.oDocument.Code }).ToList();

You need to select an anonymous type object (to project required fields) and then bind that to your gridview like:

var list = (from p in persons
            select new 
                   {
                   Name = p.Name,
                   DocumentCode = p.Document.Code
                   }).ToList();

dgvPersona.DataSource = list;

You may select the Id as well and keep it in a hidden column in your gridview , so that later you can use it for record updating etc.
