Datalist autocomplete from database in jQuery

Datalist autocomplete from database in jQuery, someone asked me to explain?

In this article I will show you how to use datalist to create jQuery autocomplete multiple values from database. You should make an Ajax call to server method GetCompanyList() and fetch company name and city from the customer table and return as JavaScript object bind into datalist element with values and label.

Here I am using Northwind database. You can download it from following link.

Download Northwind Database

Open Microsoft sql management studio and right click on the database and attach it.

Step 1: Create an entity data model using table Customer and generate entity for that.

Step 2: Right click on the "Controllers" folder and add "Home" controller. Copy and paste the following code.


public ActionResult Index()

            return View();

        public JsonResult GetCompanyList(string criteria)
            models db = new models();
            var query = (from c in db.Customers
                         where c.CompanyName.Contains(criteria)
                         orderby c.CompanyName ascending
                         select new { c.CompanyName, c.City }).Distinct();
            return Json(query.ToList(), JsonRequestBehavior.AllowGet);

Step 3: Right click on the HomeControllers and create an index view. Copy and paste the following code.


<script type="text/javascript" src=""></script>
<script type="text/javascript">
    $(document).ready(function () {
        $("#companyName").on("input", function () {
            var options = {};
            options.url = "/autocomplete/getcompanylist";
            options.type = "GET";
   = { "criteria": $("#companyName").val() };
            options.dataType = "json";
            options.success = function (data) {
                for (var i = 0; i < data.length; i++) {
                    $("#companyList").append("<option value='" +
                    data[i].CompanyName + "' label=" + data[i].City + "></option>");
<div style="border: 1px solid #DED8D8; width: 450px; height: 300px;padding-left:15px; font-family: Arial;">
    <h1>Datalist autocomplete from database in jQuery</h1>
    <input id="companyName" list="companyList" />
    <datalist id="companyList"></datalist>
