What is a TelerikGrid that uses an asynchronous datasource?

edit

A TelerikGrid that uses an asynchronous datasource is a type of grid widget from the Telerik UI for ASP.NET AJAX suite that is designed to work with data sources that offer asynchronous loading of its data. This means that it automatically retrieves data from the datasource and refreshes the grid without the need for the page to refresh, resulting in a smoother user experience. The asynchronous datasource typically allows the grid to handle large volumes of data with efficient paging, filtering, sorting, and other data manipulation options.
