dataGridView1.Columns.Add(Convert.ToString(2), "ColumnName3");

Creating Rows For the datagridview

dataGridView1.Rows.Add();

Imp: rows must be add only after the column created otherwise error will be occurred.

To Count No of rows

dataGridView1 .Rows.Count();

dataGridView1.Rows[0].Cells[0].Value = "Hello";

dataGridView1.Rows[0].Cells[1].Value = "Dear";
