This document provides instructions for adding sorting and paging functionality to a GridView control in an ASP.NET web form application. It describes dragging a GridView onto the web form, connecting it to a data source, enabling sorting and paging checkboxes in the GridView task menu, and modifying the page size property to control how many rows display per page. Changing the page size value allows viewing the effect of paging through multiple pages of records in the GridView.
