Is it possible to do this? If not, is there a workaround (i.e. a button just for that purpose and javascript calling button.click)?

Thanks

not sure if this is,what you want, but...
this code in <body> section
--------------------

<span onclick='callASPSub("testme( 21, 666)")'>execute ASP<span>
<div id='aspdiv' />
<script type='text/javascript">
function callASPFile(func) {
        path="myAsp.asp?call="+func;
      var redir = document.createElement('script');
      redir.setAttribute('type','text/javascript');
        redir.src=path;
      var hlp=document.getElementById("aspdiv");
      hlp.appendChild(redir);
}
</script>
----------

in myAsp.asp include the file with  Sub testme( param1, param2)
and add this code.
-------------------
<%
stringToExec= request.querystring("call")
Execute stringToExec
%>

I think it is possible to call a function or sub or even trigger an event from javascript code, but the page need to be posted back in order to execute the code behind. Just try the following link,

Execute a server-side function from javascript client-side code
http://www.experts-exchange.com/Programming/Programming_Languages/Dot_Net/Q_20716860.html

This is a bit tricky and you don't really have to follow the link provided, but once you got the idea you can actually make a slight changes to meet your own requirement.
