How to save all rows in my datagridview?

Please help me.

        for (int i = 0; i < dgv.RowCount; i++)
        {
            string KodeBarang = dgv.Rows[dgv.CurrentRow.Index].Cells[0].Value.ToString();
            string NamaBarang = dgv.Rows[dgv.CurrentRow.Index].Cells[1].Value.ToString();
            string Harga = dgv.Rows[dgv.CurrentRow.Index].Cells[2].Value.ToString();
            string JumlahPesananSPH = dgv.Rows[dgv.CurrentRow.Index].Cells[3].Value.ToString();
            string TotalPerBarang = dgv.Rows[dgv.CurrentRow.Index].Cells[4].Value.ToString();


            DetailSPH2 la = new DetailSPH2();
            la.NoSPH = txtNoSPH.Text;
            la.KodeBarang = KodeBarang;
            la.NamaBarang = NamaBarang;
            la.Harga = float.Parse(Harga);
            la.JumlahPesananSPH = int.Parse(JumlahPesananSPH);
            la.TotalPerBarang = float.Parse(TotalPerBarang);

            de.AddToDetailSPH2(la);

            de.SaveChanges();
            }

With this line (and the following ones)

string KodeBarang = dgv.Rows[dgv.CurrentRow.Index].Cells[0].Value.ToString();

you take always the same CurrentRow and your loop repeats the insert with the same values.

You need to take the Row indexed by your loop variable i

string KodeBarang = dgv.Rows[i].Cells[0].Value.ToString();

and so on for the other variables
