Change number of rows

Hello
I have a database with lots of items and I would like to load them from a datatable. I want to load the items little by little. When the user changes of page, I'll get only the items which must be in that page (because if I load all the items at first, the web page'll spend lots of time to load). Given that I want to get a few items but in the database there are more, I have to change the number of total items because the datatable thinks only they are the loaded items but actually, there are more items.

Thanks
