MaintainScrollPositionOnPostback

dstrange · Jul 15, 2009

This works great when a page hits a postback but is there a way for this option to work if I click a link on the page that reposts to the same url but with a querystring attached? Thanks in advance.

Something like this?

All the <br /> tags are create a scroll bar (quick and dirty way).

The onload event needs to grab the value from the qs using what ever server side language you are using (i.e)

Code:

<body onload="scrollTo(<%=request.querystring("vScroll")%>">

PHP:

<body onload="scrollTo(<%?php $_GET["vScroll"] ?>">

Here's one solution for the scrolling

Code:

<html>
<head>
<script language="javascript">
	function goToUrl(strInput) {
		vScrollPos = document.body.scrollTop;
		document.location.href = strInput + "?vScroll=" + vScrollPos;
		return false;
	}
	function scrollTo(intScrollPos) {
		document.body.scrollTop = intScrollPos;
	}
</script>
</head>
<body onload="scrollTo(valueFromQueryString);">
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<a href="myUrl" onclick="return goToUrl('test.html');" >Click</a>
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />
</body>
</html>
