推荐答案

您应保持生成的行的状态.
当然，您不能通过JavaScript使用ViewState或Session(至少我不知道该怎么做).
但是您仍然可以为此目的使用HiddenField，因为您可以通过JavaScript在客户端设置该值，并可以通过使用HiddenField ID在服务器端获取该值.

您应该在HiddenField中维护数据，并且在每个回发中都应该从保存在HiddenField中的数据中生成数据.

You should maintain the state of generated Rows.
Of course you can not use ViewState or Session through JavaScript ( At least I don''t know how to do that ).
But still you can use HiddenField for this purpose because you can set there value at client side by JavaScript and can get there value at Server side by using HiddenField ID.

You should maintain data in HiddenField and on every Postback should generate them from that data that was saved in HiddenField.
