javascript dialogbox not showing Top data
<p>I have following javascript function</p>

<pre><code>function getPopup1(redirectString) {

        window.showModalDialog(redirectString , null,
'status:no;dialogWidth:700px;dialogHeight:900px;dialogHide:true;help:no;scroll:1;edge:sunken');
    }
</code></pre>

<p>The redirect string is redirecting to an .aspx page. The page has a lot of contant so I enabled the scroll bars, but I am getting the page scrolled to end on pageload. 
How can I show the data from top.</p>
