in gmail if you check mark email 4 then move to different set of 50 or 25 records and mark selection 26 then both 4 and 26 are retained if you move back and forth.
How does google do this?
would it be possible to do something like this in a page that brings only 50 records and when NEXT is clicked…it again goes to DB to bring next set of 50 records.
You don’t technically change pages, it’s all the same page, the content is just changed dynamically with JavaScript.
