Forms Data Controls :: Windows: Combox Box Within A Datagrid Not Populated With Data

I am doing when the form loads up

DataGridViewComboBoxColumn ComboTextCol = new DataGridViewComboBoxColumn();
ComboTextCol.Headertext = "some";
ComboTextCol.DataSource = GetEmployees().Select(e => new { Name = e.LastName + " ," + e.FirstName, ID = e.EmployeeID }).ToList();
ComboTextCol.ValueMember = "ID";
ComboTextCol.DisplayMember = "Name";
datagrid.Columns.Insert(0,ComboTextCol);

I tried this too datagrid.Columns.Add(ComboTextCol). GetEmployees gives employee data I see the column but not the the data...??
