Just access the data in the buffers of the dataset.
With native IBO there is a whole set of buffer access properties that allow
you to do this.
I think there is a tech info sheet on it on my web-site. I recommend you
give it a look there.

Not on a per row basis.

There is only one panel that is replicated at paint time with data pulled
out of the buffers on the fly.
