eval objects property

Question

i have the following two objects

public partial class ProgramObj
{
  public int id;
  public PersonObj myPerson;
}

public class PersonObj
{
   public int id;
   public string full_name;
}

I am assigning a list of ProgramObj's to a repeater from a SqlDataReader

program_list.DataSource = reader;
program_list.DataBind();

What I want to do, is access the full_name property of the PersonObj in each ProgramObj I've tried multiple things, the only thing that gets me an output value is

<%# DataBinder.Eval(Container.DataItem, "id") %>

which gets me the id of the ProgramObj, but I would like to get the name of the PersonObj, I thought

<%# DataBinder.Eval(Container.DataItem, "myPerson.full_name") %>

would work, but it doesn't appear to get me anywhere.

I also tried an ItemDataBound with

PersonObj myPerson = (PersonObj)e.Item.DataItem;
lblUserName.Text = myPerson.Full_Name_RFL;

and

<%# DataBinder.Eval(Container.DataItem, "myPerson") %>

but i get an error that it cannot cast an object of type DataRecordInternal to PersonObj. thoughts?

Your ItemDataBound should work if you do this:

PersonObj myPerson = ((ProgramObj)e.Item.DataItem).myPerson;
lblUserName.Text = myPerson.full_name;

Becausse the repeater is bound to a list of ProgramObj object the DataItem will be the ProgramObj. so you then need to get the myPerson property if you want the PersonObj object.

See the What's the deal with Databinder.Eval and Container.DataItem? article on asp.net. Also, see this GridView bound with with Properties of nested class question on here.
