void loaddgvdata() {
 try {
  sda.SelectCommand = command;
  sda.SelectCommand.Connection = connection;
  sda.SelectCommand.CommandText = "SELECT * FROM personnal";
  sda.Fill(ds, "personnal");
  dgpersonal.DataSource = ds;
  dgpersonal.DataMember = "personnal";
  dgpersonal.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
  dgpersonal.Columns[0].HeaderText = "????? ??????";
  dgpersonal.Columns[0].Frozen = true;
  dgpersonal.Columns[1].HeaderText = "???";
  dgpersonal.Columns[2].HeaderText = "???";
  dgpersonal.Columns[3].HeaderText = "???";
  dgpersonal.Columns[4].HeaderText = "???";
  dgpersonal.Columns[5].HeaderText = "???";
  dgpersonal.Columns[6].HeaderText = "???";
  dgpersonal.Columns[7].HeaderText = "???";
  dgpersonal.Columns[8].HeaderText = "???";
  dgpersonal.Columns[9].HeaderText = "???";
  dgpersonal.Columns[10].HeaderText = "???";
  dgpersonal.Columns[11].HeaderText = "???";
  connection.Open();
  dr = command.ExecuteReader();
  int rowindex = 0;
  while (dr.Read()) {
   var inputname = dr["name"].ToString();
   var passwordname = password;
   var resultname = AesCryptography.DecryptText(inputname, passwordname);
   dgpersonal.Rows[rowindex].Cells[1].Value = resultname;
   var inputlname = dr["lname"].ToString();
   var passwordlname = password;
   var resultlname = AesCryptography.DecryptText(inputlname, passwordlname);
   dgpersonal.Rows[rowindex].Cells[2].Value = resultlname;
   var inputdadname = dr["dadname"].ToString();
   var passworddadname = password;
   var resultdadname = AesCryptography.DecryptText(inputdadname, passworddadname);
   dgpersonal.Rows[rowindex].Cells[3].Value = resultdadname;
   var inputbirth = dr["birth"].ToString();
   var passwordbirth = password;
   var resultbirth = AesCryptography.DecryptText(inputbirth, passwordbirth);
   dgpersonal.Rows[rowindex].Cells[4].Value = resultbirth;
   var inputidnum = dr["idnum"].ToString();
   var passwordidnum = password;
   var resultidnum = AesCryptography.DecryptText(inputidnum, passwordidnum);
   dgpersonal.Rows[rowindex].Cells[5].Value = resultidnum;
   var inputidmeli = dr["idmeli"].ToString();
   var passwordidmeli = password;
   var resultidmeli = AesCryptography.DecryptText(inputidmeli, passwordidmeli);
   dgpersonal.Rows[rowindex].Cells[6].Value = resultidmeli;
   var inputtahsil = dr["tahsil"].ToString();
   var passwordtahsil = password;
   var resulttahsil = AesCryptography.DecryptText(inputtahsil, passwordtahsil);
   dgpersonal.Rows[rowindex].Cells[7].Value = resulttahsil;
   var inputjob = dr["job"].ToString();
   var passwordjob = password;
   var resultjob = AesCryptography.DecryptText(inputjob, passwordjob);
   dgpersonal.Rows[rowindex].Cells[8].Value = resultjob;
   var inputpay = dr["pay"].ToString();
   var passwordpay = password;
   var resultpay = AesCryptography.DecryptText(inputpay, passwordpay);
   dgpersonal.Rows[rowindex].Cells[9].Value = resultpay;
   var inputmony = dr["mony"].ToString();
   var passwordmony = password;
   var resultmony = AesCryptography.DecryptText(inputmony, passwordmony);
   dgpersonal.Rows[rowindex].Cells[10].Value = resultmony;
   var inputaddres = dr["addres"].ToString();
   var passwordaddres = password;
   var resultaddres = AesCryptography.DecryptText(inputaddres, passwordaddres);
   dgpersonal.Rows[rowindex].Cells[11].Value = resultaddres;
   rowindex++;
  }
 } catch (SqlException ex) {
  MessageBox.Show(ex.Message);
 } finally {
  connection.Close();
  dr.Close();
 }
}

This is my code and when click save button , call loaddgvdata()
