Some frameworks come with built-in paging buttons in their grids that you cannot customize. This limits a developers ability to design UI's the way he/she wants. Some frameworks have the API's for paging and developers have to do the rest themselves.
In Formspider, we have best of the both worlds. You can build your own paging implementation using Formspider paging API's or you can use Formspider paging components and implement paging in your data grids with no coding. However Formspider paging components are independent of the grid. You can place these components anywhere you want on the screen. So you still have the flexibility to design your UI the way you want.
