How do I use this value in another form. I can double-click the row in the grid view

 public void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
           
         string PID=   dataGridView1.Rows[e.RowIndex].Cells[2].Value.ToString();

         persalary j = new persalary();
         j.ShowDialog();
        }
