If you going to use this cursor with Data Grid, then I think better make not
ForwardOnly, but Random. Bevause you may want scroll forward and back.
About populate ... Not sure what you ask about.
Have you check our examples? VNET/VB ?
Yes you must GO TO Nth record
Then read values from fields.
This is fast enough, than more for client side cursor
