asp.net mvc Ajax.BeginForm

I'm having some difficulties with Ajax.BeginForm

I have something like this in a view

  <% using (Ajax.BeginForm("ActionName", null , null, new { id = "FormName" }))
     {%>
      <input type="hidden" value = '<%= Html.Encode( Model.id) %>' name="id"/>
      <textarea id="message" name=message rows="4" style="width: 90%"> 
      </textarea>
  <% }%}

And the action method is something like this 

    [AcceptVerbs(HttpVerbs.Post)]
    [Authorize]
    public ActionResult ActionName(int id, string message)
    {
     ....
    }

I'm trying to pass the 'id' and 'message' to the action method. I'm passing 'null' for routeValues but I dont know what to pass. Ideally I was trying to find an overload that did not require route values but took actionName and htmlattributes (for form name) but I could not find one.I don't want to add 'message' to the view-model and I do need the FormName in there for jquery operations. What is the best way to work around this problem ?

Oh, I forgot to mention, This is how I post the form

 $.post($("#FormName").attr('action'), $("#FormName").serialize(),
                               function(result) {
                                   $("#correspondingDiv").html(result);
                               }
                            );

Use this overload: http://msdn.microsoft.com/en-us/library/dd470605.aspx

Ajax.BeginForm(
    string "ActionName",
    string "ControllerName",
    new routevalues {id="IDValue",message="MyMessage"},
    new AjaxOptions {OnBegin=[someFunction], OnFailure=[failureFunction] },
    new { id = "FormName" }
)

Try:

  <% using (Ajax.BeginForm("ActionName", null))
     {%>
      <input type="hidden" value = '<%= Html.Encode( Model.id) %>' name="id"/>
      <textarea id="message" name=message rows="4" style="width: 90%"> 
      </textarea>
  <% }%}

I think you are over-complicating the the issue, ID and Message will get populated on the postback from the fields in the form so you don't need to specify them in the form declaration. You might also want to try Html.BeginForm() instead unless you really want an Ajax response.
