You can set it programmatically

Page.MaintainScrollPositionOnPostBack = true;

In the page declaration

<%@ Page MaintainScrollPositionOnPostback="true" %>

Or in the web.configs <system.web> section.

<pages maintainScrollPositionOnPostBack="true" />

The reason the page is returning to the top, is because it is being Submitted and hence reloaded.

If you want to keep the position of the page you have 2 options;

1) Use a Anchor (See: http://www.hypergurl.com/anchors.html) 2) Post your form using AJAX and then you do not need to reload the page

Option 2 is the prefered, if you are using webforms you could use an AJAX Update Panel, or if you are using MVC you can do it using JQuery.

try to setting the following page directive in your page

<%@ Page MaintainScrollPositionOnPostback="true" %>

I put a javascript:void(0) in an a tag, as shown here:

<a href="javascript:void(0)">
