Add Upload file code to an existing form

Here is the block of code I need to add the upload file code to: protected void lbtnCompletePrint_Click(object sender, EventArgs e) { [login to view URL](this, [login to view URL](), "alert", "CompletePrint();", true); if ([login to view URL] > 0) { try { if ([login to view URL] != "0" && [login to view URL] != "0") { query = "UPDATE [tbl_ShipOrders] SET [BillPrice]=" + [login to view URL] + ", [DiscountPr]=" + [login to view URL] + ", [Consignment_Notes]='" + [login to view URL] + "' WHERE Ship_order_ID=" + ((string[])Session["BILLSTATE"])[0]; DataAccess.UpdateRecord_TMS(query); string[] emailaddresses = new string[2]; emailaddresses[0] = ((string[])Session["BILLSTATE"])[16]; emailaddresses[1] = ((string[])Session["BILLSTATE"])[17]; DateTime idate = [login to view URL](((string[])Session["BILLSTATE"])[1]); string emailsentstatus = [login to view URL]; string pdfurl = [login to view URL]; if (![login to view URL]()) { pdfurl = PdfGeneration(((string[])Session["BILLSTATE"])[0] + "-" + [login to view URL]() + "-" + [login to view URL]() + "-" + [login to view URL]()); string Body = "<h1></h1><br />" + "lower word count"; emailsentstatus = [login to view URL](emailaddresses, "STC Bill Report", Body, pdfurl); } lbUpdateCalculations_Click(null, null); [login to view URL]("BILLSTATE"); [login to view URL](this, [login to view URL](), "alert", "CompletePrint();", true); [login to view URL](GetType(), "Error Occurs!", "alert('" + emailsentstatus + "')", true); } } catch (Exception ex) { [login to view URL]("Error Occurs when completing bill. " + [login to view URL], [login to view URL]); return; } } else { [login to view URL]("Can't complete! You have to Add Products!", [login to view URL]); } } Here is the upload file code: if ([login to view URL]) { if () { [login to view URL]("Please upload only image.", [login to view URL]); return; } } string date = [login to view URL]; if ([login to view URL] > 0) { [login to view URL] = dvsql[0]["ship_order_id"].ToString(); date = dvsql[0]["idate"].ToString(); } //Upload Document try { [login to view URL](fileUpload, GeneralMethods.DocumentType_ReceiptsExpenses, [login to view URL], date); } catch (Exception ex2) { [login to view URL]("Error occurs when uploading document: " + [login to view URL](), this); } I am having issues with the form code using GridView1 and not dvsql, I am rusty on this so I need someone to put the upload code into the block of code so it uploads the file into the correct path when pressed.
