Description
This sample shows how to implement paged views with the FlexGrid. All the work is done by the CollectionView class used as a data source for the grid. To enable paging, set the PageSize property of FlexGrid or CollectionViewService. To switch pages, use the Pager Control and set Pager.Owner property to the id of FlexGrid or CollectionViewService.
Note: That the paging UI is implemented outside of the grid. This gives you complete control over the appearance and functionality of the paging mechanism. To customize the Pager by Javascript, please refer the client CollectionView class.
