Что я уже пробовал:

            using (SqlConnection openCon = new SqlConnection(con))  
            {  
                SqlDataReader reader;  
                SqlCommand cmd = new SqlCommand("SELECT memorandum from dbo.podaci_o_korisniku");  
                  
                cmd.Connection = openCon;  
                openCon.Open();  
                reader = cmd.ExecuteReader();  
  
                while (reader.Read())  
                {  
                    byte[] ap = (byte[])podaci_o_korisnikuDataGridView.SelectedRows[0].Cells["memorandum"].Value;  
                    memorandum = reader[0].ToString();  
  
                }  
                openCon.Close();  
            }
