//to send the your combox id in database to fatch name and other detail

 SqlCommand cmdd = new SqlCommand("Select * table where studentid='" + Combobox1.selectedvalue + "'", LiveCon);
                          SqlDataAdapter adpp = new SqlDataAdapter(cmdd);
                          DataTable dtr = new DataTable();
                          adpp.Fill(dtr);
                          if (dtr.Rows.Count > 0)
                          {
