OnPageChange
Viewer interaction
Description
Fires with NewPage whenever the current page changes, after LoadFromFile, page navigation such as GoToPage, NextPage and PrevPage, and form field focus moving to another page
In continuous display mode the current page also follows scrolling, so the event fires when the page under the centre of the viewport changes
