That's how the DG works, by design, and the main reason for using it 
over a collection of nested groups.

The DG will only populate rows as they are brought into view.  At any 
given time the number of rendered rows = the number of visible rows.

I once made a media browser that allows access to 2600 images, and the 
DG handled it like a champ.
