对于下拉选择索引你必须使用jquery

For dropdown selected index you have to use jquery

@Html.DropDownListFor(model => model.StateID, Enumerable.Empty<SelectListItem>(), "--Select State--")

<script type="text/javascript">

（'＃CountryID'）。change（function（）{
var selectedCountry =

('#CountryID').change(function () { var selectedCountry =

（this）.val（）;
if（selectedCountry！= null&& selectedCountry！=''）{

(this).val(); if (selectedCountry != null && selectedCountry != '') {
