Bind datagridviewcomboboxcolumn with generic collection

Hi,

I want to bind the following class as a collection of objects to a datagridview with one column as combobox.

public class GridClass
{
        [DisplayName("ID")]
        public string Id { get; set; }

        [DisplayName("First Name")]
        public string FirstName { get; set; }

        [DisplayName("Last Name")]
        public string LastName { get; set; }

        [DisplayName("Gender")]
        public List Gender { get; set; }

        public GridClass(string val)
        {
            Id = val;
            FirstName = "FirstName" + val;
            LastName = "LastName" + val;
            Gender = new List();
            Gender.Add("MALE" + val);
            Gender.Add("FEMALE" + val);

        }
}

I created a datagridview called datagridview1.
Created 5 object of gridclass as follows

                BindingList BindList = new BindingList();
            for (int i = 1; i <= 5; i++)
            {
                GridClass g = new GridClass(i.ToString());
                BindList.Add(g);
            }
I binded to datagridview.
            dataGridView1.DataSource = BindList;

But it is displaying only 3 columns ID, First Name and LastName.

I want to display Gender in combobox with each row will have different set of values.

Kindly reply for this post.

Thanks in advance

BindingList BindList = new BindingList();
        void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
        {
            foreach (DataGridViewRow row in dataGridView1.Rows)
             {
                 if ((row.Cells[1] as DataGridViewTextBoxCell).Value != null)
                   {
                    foreach (GridClass gc in BindList)
                    {
                        if (gc.FirstName.ToString() == (row.Cells[1] as DataGridViewTextBoxCell).Value.ToString())
                        {
                          (row.Cells[3] as DataGridViewComboBoxCell).Items.Clear();
                          (row.Cells[3] as DataGridViewComboBoxCell).Items.Add(gc.Gender[0].ToString());
                          (row.Cells[3] as DataGridViewComboBoxCell).Items.Add(gc.Gender[1].ToString());
                          break;
                        }

                    }
                }

            }

}

        public Form1()
        {
            //private DataGridView dgv;
            InitializeComponent();
            this.dataGridView1.DataBindingComplete += new DataGridViewBindingCompleteEventHandler(dataGridView1_DataBindingComplete);

            DataGridViewComboBoxColumn comboboxColumn = new DataGridViewComboBoxColumn();
            comboboxColumn.DataPropertyName = "Gender";
            comboboxColumn.HeaderText = "Gender";
            dataGridView1.Columns.Insert(0, comboboxColumn);

           for (int i = 1; i <= 5; i++)
            {
                GridClass g = new GridClass(i.ToString());
                BindList.Add(g);
             }
            dataGridView1.DataSource = BindList;
            dataGridView1.BindingContext = new BindingContext();

}
