Mathew，


你需要记住页面之间所选项目的内容。



这意味着你要去必须将产品ID存储在服务器上或Cookie或隐藏字段中的某处。


如果将此值存储在服务器上，您将使用Session ...它很简单，让你记住表格之间的这些信息。


查看会话：如何在网页之间传递信息以获取更多信息。


干杯！

Hi Mathew ,

You''re going to need to remember what the selected item was between the pages.


This means that you''re going to have to store the productID somewhere either on the Server or in a Cookie or Hidden field or something.

If you store this value on the server you''d be using Session...it''s pretty easy and will let you remember this information between forms.

Check out Sessions: How to pass information between web pages for more information.

Cheers!
