Events sorrounding a page click in tree grid

I am using a tree grid with pagination.
I want to be able to enable fast operations for the tree grid, before the rendering (of new set of rows ) starts when a new page is clicked. I also want to stop fast operations and refresh grid filters after the new page is rendered.
Are there events sorrounding the render of rows on a new page, after the page is clicked ?

Please help.
Thanks

Fast operations are incompatible with paging. Paging increases loading performance itself. It has not sence you use fast operations additioanlly.

It is more about having the new rows rendered when a new page is clicked in the same manner,
as in fast operations mode (with events like onCellChanged suppressed)
I am having problems, because when the new rows from a fresh page are being rendered, onCellChanged event is being called for every cell !

Try to attach “onCellChanged” event with following way:

grid.load(url,function(){ grid.attachEvent("onCellChanged",....) })
