Show 1000 records in List.

Hi All,
As a business requirmnet i have to show 1000 record per page in a list , i want to give them a scroll bar in a grid and 100 record initially and as they scroll down more record will be apended in the list .
Looking for any idea if some one has alraedy implimented like this.

In the London Theme, ther's a sample for 'infinity scroll', see thies demo page, it is done with the webblock widget 'InfiniteScroll'.
Thanks Matthias...
