This is perfect code but it cannot add a new row:

dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;

But this code can insert a new row:

var index = this.dataGridView1.Rows.Add();
this.dataGridView1.Rows[index].Cells[1].Value = "1";
this.dataGridView1.Rows[index].Cells[2].Value = "Baqar";
