[Gambas-user] Gridview_data - when is it finished?

[bb]

Is there a way to detect when the gridview_data events have all
finished?

I have a db query that returns between a few and upto 11,000 rows, so I
am loading the grid using the data event handler. After all the visible
grid rows are loaded I need to do some summary processing.

It would be rediculous to do it after each cell is loaded. But how do I
know when it is finished (for the moment)?
