       arka_data dta  = new arka_data();

       for (int i = 0; i < dataTable.Rows.Count; i++)

      {

          dta.NR = int.Parse(txtnrfatures.Text);

          dta.VLERATVSHTOTAL = float.Parse( textBox1.Text);

          dta.BARKODI = int.Parse(dataTable.Rows[i][0].ToString());

          dta.EMERTIMI = dataTable.Rows[i][1].ToString();

          dta.SASIA = int.Parse(dataTable.Rows[i][2].ToString());

          dta.CMIMI = int.Parse(dataTable.Rows[i][3].ToString());

          dta.TVSH = int.Parse(dataTable.Rows[i][4].ToString());

          dta.NENTOTALI = float.Parse(txttotali.Text);

          dta.ZBRITJA = float.Parse(txtzbritja.Text);

          dta.TOTALI = float.Parse(totali.Text);

          dta.KOHA = DateTime.Now;

          dta.KASIERI = lbluser.Text;

          dta.KLIENTI = cmbklienti.Text;

          dta.VLERAETVSH = float.Parse(dataTable.Rows[i][7].ToString());

          dta.VLERAPATVSH = float.Parse(dataTable.Rows[i][6].ToString());

          dta.NRATIKUJVE = int.Parse(lblnumri.Text);

          dta.TOTALIPCS = float.Parse(dataTable.Rows[i][5].ToString());





      }

The idea it that this class handle the data from form one , and use it(insert it into sql) on form two . How should I pass the object in another form, or how should I refer it. Also another question is the class populated correctly (from : textbox, labels and datagridview ). The method mbushe collects data , and this data should be passed one frm2. I created the method on frm1 , but don't have any clue how to cont. on. I tried Arka. Mbushe but getting this error ' is a 'method', which is not valid in the given context'The idea is that during the insertion of data on frm2 I use this data like this

           cmd.Parameters.Add(new SqlParameter("@nrfatures", mbushe.NR);

But mu question is how to get this data on frm2 and use this data during the insertion process.
