When web pages are posted back to the server, by default user is returned to
the top of the page. On a large web page, you might have a requirement to scroll
down the user automatically to the last position on the page.
MaintainScrollPositionOnPostBack page property can be used to achieve this
in one of the following ways.
- Application level: To set the property by default for all
pages in the website, open web.config and add the attribute to the pages
- Page Level: for a particular page, open the aspx and set
<%@ Page MaintainScrollPositionOnPostback="true" ...
- Code level: to set the property
Hope this helps.
