Hi Priya,

As per your requirement you have all page info in client side. So you can use cookie or local storage. Local is best is option for you. Suppose there is a page called Page1.aspx and it contains a gridview.

A user came and select some records in gridview. Then it redirects to other page. Before redirecting to other you need to store all info(checked records) in local storage. You need to call javascript function using body onunload function:

Then when a user comes to this page again you need to fetch from localStorage object and check the gridview records which are checked previously.

Please go through below link how to store data in local storage:
