Infinite Scrolling
Documentation
The DataGrid widget provides a capability to navigate from a page to a page gradually without using a pager. For this purpose, an infinite scroll mode has been introduced. Data pages in this mode are loaded when the scroll bar reaches the end of its scale. This demo illustrates how you can enable the infinite scroll mode.
Feel free to share demo-related thoughts here.
