i have been trying to find a good way to maintain the scroll position on a page after an UpdatePanel async postback. i tried a couple options:
Page.MaintainScrollPositionOnPostBack = True
and the web.config method:
<pages smartNavigation="true" maintainScrollPositionOnPostBack="true" ></pages>
but neither works.
i have a GridView inside the UpdatePanel and after every Submit button click the screen flashes and jumps to the top of the page. i then have to scroll back down to see the results of the query.
has anyone found a way to save the location of the page in codebehind, then reload the scroll position to where original submit query was initiated on the page?

place ahidden input on your page
<input runat="server" type="hidden" id="hdnScrollTop" value="" />
suppose your update panel is on a div with id DataDiv call a script from the div
and the script is
var div = document.getElementById('DataDiv');
var input = document.getElementById("hdnScrollTop");
and now add anothe script to get the position on postback
register the script on page load
ClientScript.RegisterStartupScript(this.GetType(), "ScrolPosition", "<script>ScrolPosition('DataDiv','ctl00_cphMain_hdnScrollTop');</script>");
"ctl00_cphMain_hdnScrollTop" is the hidden feild running id make the corresponding changes in your id and run it safely

Usually People loves to maintain the scroll postiion. But requirment is reverse, Here is the trick, create an script tag after the scriptmanager and put the following lines:
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm._scrollPosition = null;

result: the page posts to the top of the page after a partial postback.
the page posts to the top of the page after a partial postback.
these two links are the same solution, located at different sites. the page posts to the top of the page after a partial postback.
the best option so far is to simply use the web.config option. the position on the page is maintained after a partial postback, however, the page flashes (flickers) badly after the asynchronous postback. if i can find a fix for the flicker, i will have
a complete solution. thanks to everyone, but still looking.
