As I understand it, ComboBox columns are more dynamic for binding in DataGridView than standard columns, and this flexibility can be used to use DisplayMembers from second-order properties. This approach is the first mentioned here by Mr. Aghaei.

However, I’m not getting it right. My application still throws the exception that “Name” doesn’t exist.

 public void CreateEmployeeTable()
        {

            DataGridViewComboBoxColumn jobTitleColumn = new DataGridViewComboBoxColumn();
            jobTitleColumn.HeaderText = "Job Title";
            jobTitleColumn.DataPropertyName = "JobTitle";
            jobTitleColumn.DisplayStyle = DataGridViewComboBoxDisplayStyle.Nothing;
            jobTitleColumn.DataPropertyName = "ID";
            jobTitleColumn.DataSource = globalEmployeeList;
            jobTitleColumn.ValueMember = "ID";
            jobTitleColumn.DisplayMember = "Name";
            jobTitleColumn.ReadOnly = true;

            employeeGridView.AutoGenerateColumns = false;
            employeeGridView.ColumnCount = 2;
            employeeGridView.Columns(0).HeaderText = "Employee ID";
            employeeGridView.Columns(0).DisplayIndex = 0;
            employeeGridView.Columns(0).DataPropertyName = "ID";
            employeeGridView.Columns(1).HeaderText = "Name";
            employeeGridView.Columns(1).DataPropertyName = "ListView";
            employeeGridView.Columns(1).AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
            employeeGridView.Columns.Add(jobTitleColumn);
            
            employeeGridView.DataSource = globalEmployeeList;                                                                               
        }

Here is the class definition:

     
    public class EmployeeModel
    {
        public int ID { get; set; }
        public string LastName { get; set; }
        public string FirstName { get; set; }
        public string Nickname { get; set; }
        public DepartmentModel Department { get; set; }
        public TitleModel JobTitle { get; set; }
        public DateTime HireDate { get; set; }
        public List<EmailModel> EmailList { get; set; } = new List<EmailModel>();
        public List<PhoneModel> PhoneList { get; set; } = new List<PhoneModel>();
        public List<RestrictionModel> RestrictionsList { get; set; } = new List<RestrictionModel>();
        public List<CitationModel> CitationsList { get; set; } = new List<CitationModel>();
        public List<CertificationModel> CertificationList { get; set; } = new List<CertificationModel>();

        public string ListView
        {
            get
            {
                return $"{LastName}, {FirstName}";
            }
        }

        public string ToEmailString()
        {
            IEnumerable<string> employeeEmailStrings = EmailList.Select(emmod => emmod.ToString());
            string employeeEmailString = string.Join($"{Environment.NewLine}", employeeEmailStrings);

            IEnumerable<string> certificationStrings = CertificationList.Select(clistmod => clistmod.ToString());
            string certificationString = string.Join($"{Environment.NewLine}", certificationStrings);

            IEnumerable<string> phoneStrings = PhoneList.Select(plistmod => plistmod.ToString());
            string phoneString = string.Join($"{Environment.NewLine}", phoneStrings);

            return $"{FirstName}, {LastName}: {Environment.NewLine} -{JobTitle.Name}- {Environment.NewLine} {employeeEmailString} {Environment.NewLine} {certificationString} {Environment.NewLine} {phoneString}";
        }



        public class EmailModel
        {
            public int ID { get; set; }
            public string Address { get; set; }
            public string Type { get; set; }

            public override string ToString()
            {
                return $"{Address} ({Type})";
            }
        }

        public class PhoneModel
        {
            public int ID { get; set; }
            public string Number { get; set; }
            public string Type { get; set; }
            public override string ToString()
            {
                return $"{Number} ({Type})";
            }

        }
    }

And the definition for TitleModel:

    public class TitleModel
    {
        public string Name { get; set; }
        public int ID { get; set; }  

    }
}
