TIWCGJQGridOptions.OnPaging Property
This event fires after click on [page button] and before populating the data. Also works when the user enters a new page number in the page input box (and presses [Enter]) and when the number of requested records is changed via the select box. To this event we pass only one parameter pgButton See pager. If this event return 'stop' the processing is stopped and you can define your own custom paging
