It is very easy to call javascript function from code behind asp.net .

In .cs code write

C#

string url = "yourpage.aspx?ManiFestNumber=" + value;
               ScriptManager.RegisterClientScriptBlock(this, GetType(), "rates", "openWindow('" + url + "');", true);

in aspx page just write in this code

<script type="text/javascript">

    function openWindow(url)
{
    var w = window.open(url, '', 'width=1,height=1,toolbar=0,status=0,location=0,menubar=0,directories=0,
resizable=0,scrollbars=0');
    w.focus();
}

and Its done .........
