DataGrid

Hi All,

I have a datagridview control which populate from my object collections, then each objects have a property that consist of another object collection.
Something like:

public class Header
    {
        private int ID;
        private string formName;
        private DateTime dateLog;
        private string parentIdentifier;
        private string childIdentifier;
        private List<Details> logDetails = new List<Details>();
    }

Question:
Is there any way to expand/collapse datagridRow like treeview to view the child object collection?

Is this posible using datagridview control??

Or is there any other way to view both the Collection Parent objects and the collection of Child objects.

My Propersor don't allow me to use datasets.
Anyone can please help me.
Thanks,
