SqlConnection objConnection = newSqlConnection("Server=ASAD-2DB92FD23F;Database=VamDB;Integrated Security = True");

SqlDataAdapter objDataAdapter = newSqlDataAdapter();

objDataAdapter.SelectCommand = newSqlCommand();

objDataAdapter.SelectCommand.Connection = objConnection;

objDataAdapter.SelectCommand.CommandText = "INSERT INTO Ghest (Id,ShOzviat, SalId, MahId, VztShkhs, MGhestSar, GhestVam,Asar) VALUES (@Id,@ShOzviat,@SalId,@MahId,@VztShkhs,@MGhestSar,  @GhestVam,@Asar) ";

objDataAdapter.SelectCommand.CommandType = CommandType.Text;

objConnection.Open();

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@Id", SHG);

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@ShOzviat", dataGridView1.Rows[i].Cells[0].Value.ToString());

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@SalId", dataGridView1.Rows[i].Cells[7].Value.ToString());

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@MahId", dataGridView1.Rows[i].Cells[3].Value.ToString());

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@VztShkhs", dataGridView1.Rows[i].Cells[2].Value.ToString());

objDataAdapter.SelectCommand.Parameters.AddWithVal  ue("@MGhestSar", dataGridView1.Rows[i].Cells[4].Value.ToString());
