and view 

@scripts.render("~/bundles/jquery") <script type="text/javascript">     $(function () {         $("state").change(function () {             $.getjson('/cascadelistcontroller/districtlist' + $('#state').val(), function (data) {                 var items = '<option>select district</option>';                 $.each(data, function (i, districttype) {                     items += "<option value = '" + districttype.value + "'>" + districttype.text + " </option> ";                 });                 $('#district').html(items);             });         });     }); </script>     @model mvcsampleapplication.models.cascadingdropdowns @{     viewbag.title = "basicdrop"; }     <h2>basicdrop</h2> @using (html.beginform()) {   <div>     <fieldset>     <legend>dropdownlists</legend>       @html.label("state")       @html.dropdownlist("state", viewbag.statename selectlist,"select state", new {id= "state"})                @html.label("district");              <div class="mycombo">          <select id ="district" name ="distrct"></select>       </div>                 </fieldset>   </div> }

when select item in first drop down list not able see items in second 1 , have used div property second dropdown list increasing width have specified width '70px' not work..

would 1 pls give suggestions on one... many in advance.

two things wrong in url:

  • missing slash "/" separating action name , id,
  • word "controller" should removed cascadelistcontroller.

$.getjson('/cascadelist/districtlist/'+ $('#state').val(),

also, advisable use url.content transform virtual server-side paths urls:

$.getjson('@url.content("~/cascadelist/districtlist/")'+ $('#state').val(),
