So...because I couldn't create a form on a asp.net page I ended up creating on in the master file outside the usercontrol form then using javascript to write the form...crap on so many levels.

Crap .NET

$('#adword_save').click(function() {
  var el = $('#submit_form');
  var form_html = '<input type="hidden" id="filename" name="filename" value="adwords.csv" />' + 
                  '<input type="hidden" id="content" name="content" value="' + $('#copy_text').val() + '" />';

  el.attr({method: 'post', action: '/some/api/location.aspx'});
  el.html(form_html);
  el.submit();
});
