解决方案

最好的办法是将基础数据存储在会话或缓存中，然后再从另一页。不要尝试将数据存储在cookie等中。

如果将GridView传递到另一个页面，请参考

这里的其他方法可以使用Session但价格昂贵。



将行从一个页面传递到另一个页面，请参阅

解决方案

Your best bet is to store the underlying data in session or cache and then reference that again from the other page. Dont try and store data in cookie etc.

In case passing GridView to another page refer

http://rajudasa.blogspot.in/2011/08/aspnet-passing-gridview-control-from.html[^]

Here other approach can be using Session but it will be expensive.

Passing Row from one page to another, refer
