The C1GridView supports rows virtual scrolling to speed up rendering when large amount of data is used.

The following properties are used in this sample:

• ScrollingSettings.VirtualizationSettings.Mode - to enable the 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).
