The DataView extension supports an endless paging mode that allows loading items on demand. To enable this functionality, the PagerSettings.EndlessPagingMode property should be set to OnClick. In this mode, the DataView extension loads more items dynamically when the 'Show more items...' button is clicked.
Switch the Endless Paging mode option to "OnScroll" to see how the DataView automatically loads items on page scrolling.
Note that in this example, we purposely pause callback processing on the server side for half a second in order to make the loading panel visible during this time.
