How can i add mvc3 Autocomplete textbox changed event same as cascading dropdownlist. Below is my code in this code i want after entering statesText data automatically cities text will be changed.

my view code.

<div style="float: left">
States Filter :
</div>
<div style="float: left; padding-removed 10px">
@Html.TextBox("Statestxt")
@Html.TextBox("Citiestxt")
</div>
<div style="padding-removed 10px; float: left">

</div>
 <script type="text/javascript">
        $(document).ready(function () {
            $("#Statestxt").autocomplete({
                source: ''@Url.Action("AutocompleteAsync")''});
                $("#Citiestxt").autocomplete({
                source: ''@Url.Action("AutocompleteCity")''
            });
        });
    </script>

**我的控制器:**

**My controller:**

[NoCache]
public ActionResult AutocompleteAsync(string term)
{ 
var suggestions = from s in Adm.states
select s.state_name;
var namelist = suggestions.Where(n => n.ToLower().StartsWith(term.ToLower()));
return Json(namelist, JsonRequestBehavior.AllowGet);
}

[NoCache]
        public ActionResult AutocompleteCity(string term)
        {
            var suggestions = from s in Adm.cities
                              select s.city_name;
            var namelist = suggestions.Where(n => n.ToLower().StartsWith(term.ToLower()));
            return Json(namelist, JsonRequestBehavior.AllowGet);
        }

如果在州"中更改了文本，则应重新填写城市自动完成功能.
谢谢.

If text is changed in States Textbox city autocomplete should be refilled.
Thanks.
