Hi toni,

Yes you can do it... Try following JS code in button click of abc.aspx

<script type="text/javascript">
    function OpenXYZ()
    {
        var w = window.open("xyz.htm");
        w.window.onload = function()
        {
            //alert( w.document.getElementById( txt1 ).value );

//DO YOUR RADIO SELECTION AND OTHER LOGIC HERE
            w.document.getElementById( btnSubmit ).click();            
        };
        return false;
    }
    </script>
