Answer 1

If DataGridViewComboBoxCell already exist:

DataTable dt = new DataTable();
dt.Columns.Add("Item");
dt.Columns.Add("Value");
dt.Rows.Add("Item 1", "0");
dt.Rows.Add("Item 2", "1");
dt.Rows.Add("Item 3", "2");
dt.Rows.Add("Item 4", "3");

for (int i = 0; i < dvg.Rows.Count; i++)
{
    DataGridViewComboBoxCell comboCell = (DataGridViewComboBoxCell)dvg.Rows[i].Cells[1];
    comboCell.DisplayMember = "Item";
    comboCell.ValueMember = "Value";
    comboCell.DataSource = dt;
};
