Isolate this demo as a stand-alone application

RadGrid's virtualization feature allows you to handle hundreds of thousands of rows without negatively impacting the user experience. The control achieves this thanks to its ItemsPerView property allowing you to control the number of items loaded at a time. Users can now scroll, as well as show, hide, resize and reorder columns without any waiting time.

This demo shows how quickly Telerik's ASP.NET DataGrid can handle user interactions with 300,000 items. You can configure the component to allow scrolling through the entire data set or only through the current page by using EnableCurrentPageScrollOnly property,.
