展开/折叠gridview
问题描述：
我有一个嵌套的gridview，它使用javascript来扩展和收缩父行以显示子行。问题是，如果我进行回发或刷新gridview崩溃。
I have a nested gridview that is using javascript to expand and contract parent rows to show child rows. The problem is that if I do a postback or refresh the gridview collapses.
答
尝试在每次行可见性时保存cookie中展开/折叠行的状态如果该选项可用，则更改 - 这意味着如果在客户端计算机上启用了cookie。
Try to save the state of the expanded/collapsed rows in a cookie everytime the row visibility changes if that option is available - meaning if cookies are enabled onthe client computer.
