Passing routeValues to Controller in MVC 3

i have this code in View

    @using (Html.BeginForm())
    {
       @: Location @Html.DropDownList("territryID", (SelectList)ViewBag.Territory,    "choose one")

@Ajax.ActionLink(
    "ok",
    "Info", new { territryID = "#territryID" },
    new AjaxOptions
    {
        InsertionMode = InsertionMode.Replace,
        HttpM开发者_StackOverflow中文版ethod = "POST",
        UpdateTargetId = "post1"
    })

     <div id="post1">
     </div>
    }

and this code in my Controller

   [HttpPost]
   public ActionResult Info(int? territryID)
   {
        if (territryID == null)
        {
            return RedirectToAction("Info");
        }

        var model = (from c in _db.OCRDs
                     where c.Territory == territryID
                     select c).Distinct();

        return PartialView("_getCustomerByTerritory", model);
    }

how to passing my dropdownlist selected value to territryID parameter in controller, how to do that?

thanks, erick

How about this, initialize your URL to something like this (also note the assignment of an id to the link):

@Ajax.ActionLink("ok", "Info", new { territryID = "REPLACEME" }, new AjaxOptions { InsertionMode = InsertionMode.Replace, HttpMethod = "POST", UpdateTargetId = "post1" }, new { id = "oklink" })

Replace the placeholder (REPLACEME) when the dropdown changes, like so:

<script>
$('#territryID').change(function () {
    var newid = $('#territryID').val();
    var oldLink = $('#oklink').attr('href');
    var newLink = oldLink.replace('REPLACEME', newid);
    $('#oklink').attr('href', newLink);
});
</script>
