Are you saying that if I have a collection of objects that I would
HAVE to put a max number to the number that I want?

Say I have a grid of columns and rows.
when I program do I have to say only 10 loaded at a time and write
paging functionality.
Instead of adding one to the list programaticallty?

what about something like this?

Perhaps I have been spoiled by dot net :P or is this a limitation I
need to learn to live with?
