Client-side Paging

CollectionView Paging (Vue)

Paging is a common technique for dealing with large collections of data.

The CollectionView class supports client-side paging by default, so you can generate grids and tables that contain only a reasonable amount of data.

To enable paging, set the pageSize property and use the moveToPage method to select the page you want to display.

The sample below incorperates the CollectionViewNavigator control to assist the user in navigating the pages of the FlexGrid control.
