                select: function (event, ui) {
                    // this is for when select autocomplete item
                    return false;
             }).data("ui-autocomplete")._renderItem = function (ul, item) {
                 // here return item for autocomplete text box, Here is the place 
                 // where we can modify data as we want to show as autocomplete item
                 return $("<li>")
                 .append("<a style='padding-left:40px; background-image:url(/CountryLogo/" + item.Logo + ");" +
                 "background-repeat:no-repeat;background-position:left center;' >" + item.CountryName + "</a>").appendTo(ul);

Step-6: Write function for fetch data from database and show in Autocomplete TextBox with image .

Import this 2 Namespace
            using System.Web.Services;
            using System.Web.Script.Services;
Write this function into your page behind.
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public static List<CountryMaster> GetCountry(string pre)
            List<CountryMaster> allCountry = new List<CountryMaster>();
            using (MyDatabaseEntities dc = new MyDatabaseEntities())
                allCountry = dc.CountryMasters.Where(a => a.CountryName.StartsWith(pre)).OrderBy(a => a.CountryName).ToList();
