Description

This sample shows how to implement paged views with the MultiRow. 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 MultiRow or CollectionViewService. To switch pages, use the Pager control and set Pager.Owner property to the id of MultiRow or CollectionViewService.

In this example, the paging happens server-side. This is because CollectionView here acts like a service and synchronizes with server data. The CollectionView internally does an ajax call to fetch next set of data. Refer Disable Server Reading sample for client-side paging.

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.
