ASP.Net validation summary causes page to jump to top

Two possible work arounds:

Disable client validation and jump to correct position on post back:

* set EnableClientScript="false" for all validation controls (disabling client validation)* set MaintainScrollPositionOnPostback="true" in Page directive

Disable the scrollTo function in javascript:

<script type="text/javascript">    window.scrollTo = function() { }</script>

This is a known bug, as documented on Microsoft Connect. The relevant issue has the basis for the best work around:

var ValidationSummaryOnSubmitOrig = ValidationSummaryOnSubmit;var ValidationSummaryOnSubmit = function() {    var scrollToOrig = window.scrollTo;    window.scrollTo = function() { };    var retVal = ValidationSummaryOnSubmitOrig();    window.scrollTo = scrollToOrig;    return retVal;}

Instead of

<script type="text/javascript">    window.scrollTo = function() { return true; }</script>

which would indiscriminately override the ScrollTo function for all postbacks, I put the function in my OnClientClick event of the button. As below.

onClientClick="window.scrollTo = function(x,y) { return true; };"

Not sure if it's the best solution, but it seems to have done the job for me.
