foreach (GridViewRow g1 in SalesInvoiceGridView.Rows)
{

string pcode = SalesInvoiceGridView.Rows[i].Cells[3].Text;
DataSet dp = da.GetDataSet( "select ProductId from Tbl_Product where ProductCode ='" + pcode.ToString() + "'");
var Gender = dp.Tables[0].Rows[0][0].ToString();
int prodid = Convert.ToInt32(Gender);
DataSet dp1 = da.GetDataSet("select Barcode from Tbl_Barcodes where Product_Id ='" + prodid + "'");
var bcode = dp1.Tables[0].Rows[0][0].ToString();
DataSet dp2 = da.GetDataSet("select Price from Tbl_Product where ProductId ='" + prodid + "'");
var pric = dp2.Tables[0].Rows[0][0].ToString();
decimal pricp = Convert.ToDecimal(pric);
DataSet dp3 = da.GetDataSet("select UnitId from Tbl_Product where ProductId ='" + prodid + "'");
var uid = dp3.Tables[0].Rows[0][0].ToString();
int u1id = Convert.ToInt16(uid);
DataSet dp4 = da.GetDataSet("select UnitName from Tbl_UOM where UnitId ='" + u1id + "'");
var uname = dp4.Tables[0].Rows[0][0].ToString();
string u1name = uname;

//var proid = da.ExecuteCmd(query);
//DataSet ds = da.GetDataSet("select ProductId from Tbl_Product where ProductCode ='" + pcode.ToString() + "'");
//if (ds.Tables[0].Rows.Count > 0)
//{

// //txtClass.Text = ds.Tables[0].Rows[0][0].ToString();
// string Gender = ds.Tables[0].Rows[0][0].ToString();
//ds = ObjectAccess.GetDataSet(query);
//var proid = ds.Tables[0];
//int customerId = int.Parse(SalesInvoiceGridView.Rows.Cells[0].Text);
