Following are the ways where the user can maintain the scroll position after a postback.

1. In the page declaration, add <%@ Page MaintainScrollPositionOnPostback="true" %> This will maintain the scroll position of that particular page only.
2. The user can even set via code behind also by including System.Web.UI.Page.MaintainScrollPositionOnPostBack = true;
