Maintaining scroll position on Treeview
Hi All,
I found this great article on maintaining scroll position
http://www.codeguru.com/csharp/.net/...le.php/c12869/
It works a treat if your not using master pages, but with a master page, it seems not to work. The reason being it wants to place an onload event in the <body> section, but of course there is no <body> section in the pages that use a master page.
I thought I'd be smart and place it in the master page <body> but this didn't work, presumably because the masterpage isn't getting posted back.
Anybody have any ideas how to maintain the scroll position when the treeview is in a container control where the page has a master page?

Re: Maintaining scroll position on Treeview
You can use the following javascript function to add scripts to the body onload event. Just inject that javascript into your page somewhere... I know this works with IE6, but I haven't tested on any other browsers. Insert a script statement after your treeview something like this
Code:
<script language="javascript">addLoadScript('LoadEvent');</script>
the function:
Code:
function addLoadScript(script)
{
if (window.onload == null)
{
window.onload=new Function(script);
}
else
{
var oldscript = window.onload.toString();
if (oldscript.substring(0,8) == 'function')
{
var start = oldscript.indexOf('{');
var end = oldscript.lastIndexOf('}');
oldscript = oldscript.substring(start + 1, end);
oldscript = Trim(oldscript);
if (oldscript.charAt(oldscript.length - 1) != ';')
{
oldscript = oldscript + ';';
}
window.onload = new Function(oldscript + script);
}
}
}
function Trim(sInString)
{
sInString = sInString.replace( /^\s+/g, "" );
return sInString.replace( /\s+$/g, "" );
}
