How to program SmartRendering events?

I’m testing the dxhtmlGrid to probably purchase entire suite.

So here is the thing:
The SmartRendering property, is used to load data to the Grid/TreeGrid component.
How can I program the events that are used to load, this part of information?
I have to much rows on my JSONObject, so I need to load that lines in parts, to not overload the browser.
With SmartRendering, I’ve loaded almost 900k rows. But it crashes the browser at 894k.
So if I load this dataset programmable in parts of 1k, I can load all these data.

Before everything, i cant use pagination, because is not accepted by my company, they need this data-flow.

Is possible to program the SmartRendering event?
