البرنامج يعمل بشكل سلس دون اي اشارة الى خطأ يذكر 




وهذا الكود و مكان وضعه في الاجراء

PHP كود :

       private void btnAdd_Click(object sender, EventArgs e)
        {
            this.ID_Orders.Text = ORD.ADD_ID_ORDERS().Rows[0][0].ToString();
            FRM_CUST_N_ORD frm = new FRM_CUST_N_ORD();
            frm.ShowDialog();
            this.ID_Customer.Text = frm.DGV_ORD_PRNT.CurrentRow.Cells[0].Value.ToString();
            this.name_Customer.Text = frm.DGV_ORD_PRNT.CurrentRow.Cells[1].Value.ToString();
            this.comb_type_Customer.Text = frm.DGV_ORD_PRNT.CurrentRow.Cells[3].Value.ToString();
            dgv_Orders.Focus();

            btnAdd.Enabled = false;
            btn_save.Enabled = true;
            print.Enabled = true;
