With paging you can only load the necessary data to fit one page. See Paging Grid Data for details. Stealth paging is a little different; you can achieve paging functionality with a scrollbar. As the user scrolls down the grid, more data is fetched as needed, just like with paging. C1DataGrid supports server-side sorting and filtering so you can still achieve these functionalities without sacrificing performance. In this tutorial you'll create a Silverlight application with a C1DataGrid control that implements stealth paging functionality.
