The DevExpress ASP.NET Grid View (ASPxGridView) supports a virtual paging mode that allows end-users to navigate through grid pages using the vertical scroll bar.
In this demo, the Settings.VerticalScrollBarStyle property is set to VirtualSmooth, allowing the ASPxGridView to smoothly scroll data through pages when a scroll button is clicked.
The vertical scroll bar can be used with or without the built-in pager to dynamically load requested page data using callbacks.
