The DevExpress ASP.NET Data View (ASPxDataView) control supports endless paging mode, which loads items on demand. To enable this functionality, set the EndlessPagingMode property to one of the following values.
- OnClick - items are loaded on a 'Show more items' link click.
- OnScroll - items are loaded on page scroll.
Note that in this example, we intentionally pause callback processing on the server side for half a second in order to make the loading panel visible during this time.
