jQuery Display No Results (Match) Found Message in AutoComplete in Asp.Net

May 27, 2015

Here I will explain how to use
jQuery to show or display no results found message in autocomplete textbox when no matching records found in using c#, or jQuery autocomplete textbox display no records found message when no matching results found in using c#,

In previous articles I explained jQuery show or hide loading image in, jQuery autocomplete textbox with multiple words in, jQuery autocomplete with images in,
jQuery slideup, slidedown, slidetoggle effects example and many articles relating to autocomplete, css, AngularJS, jQuery, JavaScript and Now I will explain how to display no records found message in autocomplete textbox when no matching records found in jQuery using with example.

Before implement this example first design one table userdetails in your database like as shown below

Column Name
Data Type
Allow Nulls
Once we design table in our database insert some dummy data in your table to use it in our application that would be like as shown below

Now open your aspx page and write the code like as shown below

<html xmlns="">
<title>jQuery Show Records Found Message in AutoComplete</title>
<link href="" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src=""></script>
<script type="text/javascript" src=""></script>
<script type="text/javascript">
$(function () {
function SearchText() {
source: function (request, response) {
type: "POST",
contentType: "application/json; charset=utf-8",
url: "jQueryAutoCompleteTextbox.aspx/GetAutoCompleteData",
data: "{'username':'" + $('#txtSearch').val()  + "'}",
dataType: "json",
success: function (data) {
if (data.d.length >0) {
response($.map(data.d, function (item) {
return {
label: item.split('/')[0],
val: item.split('/')[1]
else {
response([{ label: 'No Records Found', val: -1}]);
error: function (result) {
select: function (event, ui) {
if (ui.item.val == -1) {
return false;
<form id="form1" runat="server">
<div class="demo">
<asp:HiddenField ID="hdnId" runat="server" />
<div class="ui-widget">
<label for="tbAuto">Enter UserName: </label>
<input type="text" id="txtSearch" class="autosuggest" />
Selected UserId:<b><label id="lblUserId" /></b>

Now add following namespaces in code behind

C# Code

using System;
using System.Collections.Generic;
using System.Web.Services;
using System.Data.SqlClient;

After completion of adding namespaces you need to write the code like as shown below

public static List<string> GetAutoCompleteData(string username)
List<string> result = new List<string>();
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
using (SqlCommand cmd = new SqlCommand("select UserId,UserName from userdetails where UserName LIKE '%'+@SearchText+'%'", con))
cmd.Parameters.AddWithValue("@SearchText", username);
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
result.Add(string.Format("{0}/{1}", dr["UserName"], dr["UserId"]));
return result;


Imports System.Collections.Generic
Imports System.Web.Services
Imports System.Data.SqlClient

Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(sender As Object, e As EventArgs)
End Sub
<WebMethod()> _
Public Shared Function GetAutoCompleteData(ByVal username As String) As List(Of String)
Dim result As New List(Of String)()
Using con As New SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB")
Using cmd As New SqlCommand("select UserId,UserName from userdetails where UserName LIKE '%'+@SearchText+'%'", con)
cmd.Parameters.AddWithValue("@SearchText", username)
Dim dr As SqlDataReader = cmd.ExecuteReader()
While dr.Read()
result.Add(String.Format("{0}/{1}", dr("UserName"), dr("UserId")))
End While
Return result
End Using
End Using
End Function
End Class
