Populate Dropdown with jquery using JSON request in asp.net mvc3

In this Article i am going to demonstrate to fill the dropdownlist with jquery using JSON in asp.net mvc3. To achieve this task we need to write the following JavaScript code in view (.cshtml page)

    ViewBag.Title = "Products";
<script type="text/javascript">

  jquery(document).ready(function () {
        jquery("ddlCategory").change(function () {

            var idModel = jquery("#ddlCategory").val();
            jquery.getJSON("product/items/", { category: idModel },
                    function (carData) {
                        var select =jquery("#ddlitems");
                        select.append($('<option/>', {
                            value: 0,
                            text: ""

                        jquery.each(carData, function (index, itemData) {

                            select.append(jquery('<option/>', {
                                value: itemData.Value,
                                text: itemData.Text



@Html.DropDownList("ddlCategory", new SelectList(new string[] { "Select", "CategoryA", "Category2" }.ToList(), "Select"))

Above code having two dropdownlist one is for category and second is for items. The logic behind above code is to fill items as per category selected above. I have used jquery change methode to fill items on change of category. On change the JSON request will be sent back to server and on response from server the items populated in items dropdownlist

in controller following code need to write

        public JsonResult Items(string category)

            var result = DB.items.Where(ce=>ce.category==category);
            var itemtdata = result.Select(m => new SelectListItem()
                Value = m.itemid,
                Text = m.itemname

            return Json(itemtdata, JsonRequestBehavior.AllowGet);


I hope that this Article help you on fill dropdown on Json request using Jquery in MVC application
