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>
