How to banging objects to gridcontrol?

For example:

class Company
{
    string name;
    public string Name
    {
       get {return name;}
       set {name = value;}
    }
}

class Group
{
    company myCompany;
    public Compay MyCompany
    {
        get {return myCompany;}
        set {myCompany = value;}
    }
}

class User
{
   string name;
   int age;
   Group myGroup;
  
   public string Name
   {
       get {return name;}
       set {name = value;}
   }

   public string Age
   {
       get {return age;}
       set {age = value;}
   }
  
   public Group MyGroup
   {
       get {return myGroup;}
       set {myGroup = value;}
   }
}

static mani()
{
//create data source
    Company company = new Company();
    company.Name = "Com";

    Group group = new Group();
    group.Name = "Test Group";

    User[ users = new User[2];

    users[0] = new User();
    users[0].Name = "Jim";
    users[0].Age = 10;
    users[0].Group = group;

    users[1] = new User();
    users[1].Name = "Tim";
    users[1].Age = 20;
    users[1].Group = group;

   // i want to display the users' informations at the same gridcontrol
   // such as: user.Name,user.age, user.MyGroup.Name, user.MyGroup.MyCompany.Name

// i coding like this  

DevExpress.XtraGrid.GridControl grid = CreateGridControl();
   AddGridColumn(grid);

   grid.DataSource = users;

}

private DevExpress.XtraGrid.GridControl CreateGridControl()
{
            //
            DevExpress.XtraGrid.GridControl grid = new DevExpress.XtraGrid.GridControl();
            DevExpress.XtraGrid.Views.Grid.GridView view = new DevExpress.XtraGrid.Views.Grid.GridView();

            //
            //
            //
            grid.EmbeddedNavigator.Name = "";
            //grid.Location = new System.Drawing.Point(25, 24);
            grid.MainView = view;
            grid.Name = "grid";
            //grid.Size = new System.Drawing.Size(400, 200);
            grid.TabIndex = 0;
            grid.ViewCollection.AddRange(new DevExpress.XtraGrid.Views.Base.BaseView[ {
            view});
            //
            // gridView1
            //
            view.GridControl = grid;
            view.Name = "view";

            grid.Visible = false;

            this.Controls.Add(grid);

            return grid;
}
 
 private void AddGridColumn(DevExpress.XtraGrid.GridControl grid)
        {
            DevExpress.XtraGrid.Views.Base.ColumnView View = grid.MainView as                            

DevExpress.XtraGrid.Views.Base.ColumnView;
            View.Columns.Clear();
            DevExpress.XtraGrid.Columns.GridColumn column;

            // user's name
            column = View.Columns.AddField("Name");
            column.Caption = "Name";
            column.OptionsFilter.AllowFilter = false;
            column.VisibleIndex = 0;
            column.OptionsColumn.AllowEdit = false;
            column.Width = 140;
            column.FieldName = "Name";

            //user's age
            column = View.Columns.AddField("Age");
            column.Caption = "Age";
            column.OptionsFilter.AllowFilter = false;
            column.VisibleIndex = 1;
            column.OptionsColumn.AllowEdit = false;
            column.Width = 140;
            column.FieldName = "Age";

            //name of user's group
            column = View.Columns.AddField("GroupName");
            column.Caption = "Group name";
            column.OptionsFilter.AllowFilter = false;
            column.VisibleIndex = 2;
            column.OptionsColumn.AllowEdit = false;
            column.Width = 140;
            column.FieldName = "MyGroup";
           
            //the company name
            //column = View.Columns.AddField("CompayName");
            //column.Caption = "Company name";
            //column.OptionsFilter.AllowFilter = false;
            //column.VisibleIndex = 3;
            //column.OptionsColumn.AllowEdit = false;
            //column.Width = 140;
            //column.FieldName = "MyGroup.Company";
           
        }

Notic:
  if i override the "ToString" of the Group like this

public override string ToString()
 {
         return this.Name;
 }

the girdcontrol can display the group's name.

but now i have no method to display the "Company.name" at the same gridcontrol by object,
how can i do ?
