AJAX GridView Paging feature can be added by using AJAX UpdatePanel control. You can place the ASP.Net GridView control inside the Update Panel control of AJAX extensions. Set the AllowPaging property of GridView control to true to render the paging at the bottom of GridView after binding the data.
