try using this: First globally declare your datatable:- public static DataTable dt = new DataTable(); put the following code inside the form load event: dt.Columns.Add(new DataColumn ( Name  typeof(string) )); dt.Columns.Add( new DataColumn( Course   typeof(string) )); dt.Columns.Add( new DataColumn (GPA  typeof(string) )); dataGridView1.DataSource = dt; Put the following code inside the button click event. DataRow dr = null; dr = dt.NewRow(); dt.[Name] = Name _comboBox.SelectedItem.ToString(); dt[Course] = Course _comboBox.SelectedItem.ToString(); dt [ GPA ] = GPA _comboBox.SelectedItem.ToString(); dt.Rows.Add(dr); dt.AcceptChanges(); dataGridView1.DataSource = dt;
