请问如何将页面的滚动条总是置于下边？

滚动条一般是在上边的，如何将起置于下边呢？谢谢啦~~~

在page_load事件里：
Page.RegisterStartupScript("js","<script>scroll(0,300000)</script>");
window.scrollTo(0,document.body.scrollHeight)
以下代码经过测试<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="gb2312" lang="gb2312">

<script language="javascript" type="text/javascript">
function aaa(){
window.scrollTo(0,document.body.scrollHeight);
}
</script>
</head>
<body id="myHtml" onload="aaa()">
<form> 
 
 
 
 
 
 
 
 
 
 
 asdasdadasd</form></body>
</html>
/页面加载时让滚动条在最下面
<body onload="javascript:window.scrollTo(0,document.body.scrollHeight)">
