Hi You have to use handle the change event using jQuery as like this in cshtml @Html.DropDownListFor(m => m.Id ListToBeBound as IEnumerable  Select One new {@id=ddl1}) $(function() { $('select#someDD').change(function() { var selectedId = $(this).val(); $.ajax({ url: 'Home/LoadSomething' type: 'POST' data: JSON.stringify({ selectedId : selectedId }) dataType: 'json' contentType: 'application/json' success: function (data) { // Do stuff here }); error: function (data) { // Do stuff here }); }); [HttpPost] public ActionResult LoadSomething(int selectedId) { //Do stuff & return value. return Json(managers); }
