How to know when sorting has completed?

[iforlife]

Hi,
I'm playing around with JS 4 to evaluate it and I can't figure out which is the event that should get fired once a sorting is done. I have this really basic grid. I've figured the last event that proves the grid has completed loading is the "afterlayout", but I can't tackle the sorting

Do you guys have any ideas how to do that?

Thanks.

I've just found the datachanged event on the Store. Worked like a charm
