title: inline delete - delOptions - how to add additional data to restful post?
body: <p>I'm looking at this documentation and wonder how do you add additional restful POST data when submitting to the server then remove a jqgrid row when success but not remove row when failed.</p>

  <p>I also saw this example but I'm not getting it on restful post.   <a href="https://stackoverflow.com/questions/2833254/jqgrid-delete-row-how-to-send-additional-post-data">jqGrid (Delete row) - How to send additional POST data?</a></p>
  
  <p>Thanks...</p>
