The following properties are used in this sample: ScrollingSettings.VirtualizationSettings.Mode - to enable both the columns and rows virtual scrolling. CallbackSettings.Action - to enable the virtual scrolling mode in which new portions of data items will be requested from the server via callbacks (when this mode is used some features like column grouping are not supported).
