Remote paging

pqPager:beforeChange event can be used to save selections on current page in a data structure ( array/ object ) and then restore them when user navigates back to same page. you would need unique id of every row to associate selections with corresponding rows.

Example for usage of beforeChange event of pager: https://paramquery.com/pro/demos/editing

Deleting or manipulating records on other pages in case of remote paging is not feasible. Please use local paging.
