c＃訂單處理ASP.NET頁
[英]c# Order Processing ASP.NET Page
問題描述
我正在構建一個ASP.NET頁面，這是一個銷售訂單處理表單，由於我缺乏使用該語言的經驗，我遇到了兩個最后的問題，希望您能為您提供幫助。
問題1-我有一個字段<asp:DropDownList runat="server" ID="txtProduct"></asp:DropDownList>從數據庫表Called Products中提取來填充其選項列表。 我需要根據產品的選擇自動拉出SalesPrice值並將其插入到txtUnitAmount字段中。
問題2-表單填寫完畢並且DataTable中有記錄后，我需要在用戶單擊按鈕時將所有行插入數據庫表SalesOrders中。

2 個解決方案

由於我無法編寫完整的代碼，因此只給您一些提示。
1. Create a class with the field name you want to insert into you DB.
Like for Sales order, whatever fields you have in your form,
create properties for the same.
2. Bind the grid and Dropdowns from the database using the datatable.
3. Put a hidden field on the form to detect insert or update process
4. On selection chnage of grid or dropdown fill the form fields,
you have for sales order. By extracting the rows from the datatable
and fill it to textboxes.
5. While save button click , create a method that will be used for filling
up the SalesOrder Class object. pass this object to data layer, extract
the properties and pass it as parameter in your AddUpadte query.

您正在使用哪個框架？ 應當設置下拉列表auto postback = true，然后創建事件SelectedIndex Change，然后編寫代碼以自動填充文本帖子（ textboxName.text = dropdownlistName.selectedItem.Tex ）。
希望能幫助到你：）
