推荐答案

当您将页面从一个页面重定向到另一个页面时。当您再次返回此页面时，您的控制值将不会保留在上一页中。



要做到这一点，你必须将所选复选框的值存储在内存中，如'Session'



当你再次回到这个页面时，检查这个会话是否有价值。如果它具有值，则可以获取复选框的值并进行检查。

When you redirect your page from one to another. your control value will not be preserved for the previous page when you come back again here.

To do this you must have to store value of the selected checkboxes in in-memory like 'Session'

and when you come back again on this page check that whether this session has value or not. and if it has values than you can get values of the checkbox and make it checked.
