我有一个gridview，我将其用作心愿单，但我希望能够让用户将他们的愿望清单中的物品添加到各自的购物车中。我已经对用户登录进行了编程以提取相应用户的心愿单，并且我编写了一个按钮来删除不需要的项目。如何编写可由用户选择的复选框，然后让用户单击CheckOut按钮将这些项目和相关信息复制到购物车？


请参阅代码下面

I have a gridview that I am using as a wishlist, but I want to have the functionality of allowing users to add their items from their wishlist to their respective shopping cart. I have programmed the user login to pull up the respective user''s wishlist and I have programmed a button to remove unwanted items. How can I program a checkbox that can be selected by the user, then have the user click on the CheckOut button to copy those items and the associated information to the shopping cart?

你好Tsubasa，


我想我来了之前你的问题，但因为我不知道你用什么作为购物车我不知道回答你问题的好起点是什么。


既然你已经发布了你的代码，那就更清楚你是什么了我试着这么做但是我还没看到购物车。


什么是你的购物车？

这是一个存储在会话中的对象？

它是数据库中的表格吗？

还有别的吗？

你有购物车吗？


无论如何，我要建议的第一件事是为复选框添加一个ID，以便您可以使用FindControl方法找到它。


然后，当用户点击结账时，按钮，循环遍历GridView中的所有行，并检查是否选中了复选框....如果是，请执行将项目添加到此购物车所需的任何操作。

Hi Tsubasa,

I think I''ve come across your question before but because I didn''t know what you were using as a "Shopping Cart" I didn''t know what a good starting point for answering your question would be.

Now that you''ve posted your code it''s a Little more clear as to what you''re trying to do but I still don''t see a shopping cart.

What is your "Shopping Cart"?
Is it an Object stored in session?
Is it a table in a database?
Is it something else??
Do you even have a shopping cart?

Anyways, the first thing I''m going to suggest is adding a ID for the checkbox so that you can locate it using the FindControl method.

Then when the user clicks the "checkout" button, loop through all of the rows in the GridView and check if the checkbox is checked....if so, do whatever you need to do to add the item to this "shopping cart".
