Jquery/Ajax autocomplete textbox not working in ASP.net

I have a text box that I am trying to have autocomplete with values from a database. The code is, however, not doing anything when I begin typing in the text box. Does anyone have any idea how to fix this? The Scripts are in the head of the page.
<asp:TextBox placeholder="Search by job title" runat="server" CssClass="search" ID="searchTitle"></asp:TextBox>
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.8.0.js"></script>
<script src="https://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.22/jquery-ui.js"></script>
<script>
$(function () {
$("#searchTitle").autocomplete({
source: function (request,response) {
var param = { posting_jobPosition: $("#searchTitle").val() };
$.ajax({
url: "jobseekerHome.aspx/GetTitles",
data: JSON.stringify(param),
type: "post",
contentType: "application/json; charset=utf-8",
datafilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) { return {value: item }}))
},
});
},
minlength: 1
});
});
</script>
[WebMethod]
public static List<string> GetTitles(string posting_jobPosition)
{
string CS = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
OleDbConnection Connection = new OleDbConnection(CS);
List<string> Titles = new List<string>();
string query = string.Format("SELECT posting_jobPosition FROM BusinessJobPosting WHERE (posting_jobPosition LIKE '%{0}%' AND isActive = true)", posting_jobPosition);
OleDbCommand oleCom1 = new OleDbCommand(query, Connection);
Connection.Open();
OleDbDataReader reader = oleCom1.ExecuteReader();
while (reader.Read())
{
Titles.Add(reader[0].ToString());
}
Connection.Close();
return Titles;
}
Thanks guys :)

One possible reason that I see is the ID. Change the id as:
$("#<%=searchTitle.ClientID%>").autocomplete({

how to bind dropdown in sharepoint using angularJS?

Hi I am developing one small application in sharepoint 2013 webparts. I am trying to bind dropdown from database using angular js. My pages are RFRegretLetterWP.ascx and RFRegretLetterWP.ascx. I have tried as below.
<script type="text/javascript">
angular.module('drpdwnApp', []).controller('drpdwnCtrl', function ($scope, $http) {
$scope.ProductList = null;
//Declaring the function to load data from database
$scope.fillProductList = function () {
$http({
method: 'POST',
url: 'RFPRegretLetterWP.ascx/GetDDLNames',
data: {}
}).success(function (result) {
$scope.ProductList = result.d;
});
};
//Calling the function to load the data on pageload
$scope.fillProductList();
});
</script>
This is my html code.
<div ng-app="drpdwnApp" ng-controller="drpdwnCtrl">
<select ng-model="drpdpwnvalue" ng-options="item.OrderID for item in ProductList">
<option value="" label="Select and item"></option>
</select>
</div>
This is my server side code.
public static List<OrderList> GetDDLNames()
{
List<OrderList> list = new List<OrderList>();
using (SqlConnection conn = new SqlConnection("I have connection string here"))
{
conn.Open();
string strquery = ("select * from CategoryMaster order by CategoryName Asc");
using (SqlCommand cmd = new SqlCommand(strquery, conn))
{
SqlDataReader reader = cmd.ExecuteReader();
while (reader.Read())
{
OrderList objorder = new OrderList(reader["Vendor_ID"].ToString());
list.Add(objorder);
}
}
}
return list;
}
public class OrderList
{
public string Vendor_ID;
public OrderList(string UName)
{
Vendor_ID = UName;
}
}
I have little doubt in making call to server. This is my Url
url: 'RFPRegretLetterWP.ascx/GetDDLNames' but my page name is RFPRegretLetterWP.ascx.cs so i am having confusion. In some articles i noticed [System.Web.Services.WebMethod()] but when i put it it gives me error. May I have some suggestions on this regards. thank you for consideration

I suggest you to insert the server side code into a LayoutsPage like this:
using System.Web.Services;
public partial class RFPRegretLetterWP : LayoutsPageBase
{
[WebMethod]
public static IEnumerable GetDDLNames()
{
List<OrderList> list = new List<OrderList>();
/* your code */
return list;
}
public class OrderList
{
/* your code */
}
}
and call the web method with the url:
_spPageContextInfo.webAbsoluteUrl/_layouts/15/<project name>/<pagename>.aspx/GetDDLNames
like this:
<script type="text/javascript">
angular.module('drpdwnApp', []).controller('drpdwnCtrl', function ($scope, $http) {
$scope.ProductList = null;
//Declaring the function to load data from database
$scope.fillProductList = function () {
$.ajax({
type: "POST",
url: _spPageContextInfo.webAbsoluteUrl + "/_layouts/15/<project name>/RFPRegretLetterWP.aspx/GetDDLNames",
data: null,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: true,
success: onCompleted,
error: onError
});
function onCompleted(data) {
if (data !== null)
$scope.ProductList = data.d;
}
function onError(error) {
console.log('An error has occurred: ' + error.data);
}
};
//Calling the function to load the data on pageload
$scope.fillProductList();
});
</script>
Replace <project name> with your visual studio project's name.

jquery autocomplete for multiple textboxes inside asp.net Gridview

I have asp.net Gridview that have at least 15 rows with textbox by default example
aspx
<asp:GridView ID="gv_Others" runat="server" AutoGenerateColumns="false" CssClass="gvothers">
<Columns>
<asp:TemplateField >
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<ItemTemplate >
<asp:TextBox ID="txtEmp" runat="server" Width=100% Height=22px CssClass="txtE"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
aspx.cs (here how I am generating 15 rows of a GridView)
private void SetInitialRowsofOthers()
{
var list = new List<string>();
for (int i = 0; i < 16; i++)
{
list.Add(string.Empty);
}
gv_Others.DataSource = list;
gv_Others.DataBind();
gv_Others.HeaderRow.Visible = false;
}

I want to fill each textbox by jQuery autocomplete.. for this I created a webservice and getting a value from jQuery.
How I am trying to achieve this task:

Now for example when I type "Engine Work" in TEXTBOX 1 and select the value which populated by jQuery autocomplete("Engine Work") then second time when I type in other text box (TEXT BOX 2). It's only give me the "Engine Work" option to select.. which means after selecting any value (populated by jQuery autocomplete) I can't select any other value in other text boxes....
Example:- (See Image Below)
as you see i type Genral Work but still it`s populating the Previous value "Engine Work" in jquery AutoComplete which i dont want
How to find the TextBox by CSS Class using jQuery????
Something like this (its only find TextBox id by using jQuery inside GridView but I need to find textbox by Css Class)
var $arrT = $('#<%=gv_Others.ClientID %>').find('input:text[id$="txtEmp"]');

Change your script block to this:
$(document).ready(function() {
// This selects all inputs inside the table with the txtE class and applies
// the autocomplete function to them
$('table[id$="gv_Others"] input.txtE').autocomplete({
source: function(request, response) {
$.ajax({
url: "WebService.asmx/GetAutoCompleteData",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: "{ 'txt1' : '" + request.term + "'}",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
return {
label: item,
value: item
}
}))
//debugger;
},
error: function(result) {
alert("Error");
}
});
},
minLength: 1,
delay: 1000
});
});
Look at the data: in the ajax post - it's using request.term and I changed the selector.
The issue with your jquery is this line:
data: "{ 'txt1' : '" + $($arrT).val() + "'}",
That will always return the first value of the array (the first textbox) so it's always submitting the first value to your webservice as the search text.

Sending multiple parameters to stored procedure with jQuery Ajax

I've got a web method that looks like:
[WebMethod]
public void InsertDrugNameAndColorToDatabase(string drugName,string drugColor)
{
string cs = ConfigurationManager.ConnectionStrings["dbcs"].ConnectionString;
using (var con = new SqlConnection(cs))
{
using (var cmd = new SqlCommand("spInsertDrugText", con))
{
con.Open();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#drugName", drugName);
cmd.Parameters.AddWithValue("#drugColor", drugColor);
cmd.ExecuteNonQuery();
}
}
}
and a little JS:
<script type="text/javascript">
$(document).ready(function () {
$(".drugQuizzes").draggable({ tolerance: "fit" });
$(".drugAnswers").droppable({
drop: function (event, ui) {
var drugName = JSON.stringify({ "drugName": $(ui.draggable).find("span").text() });
var drugColor = JSON.stringify({ "drugColor": $(ui.draggable).css("background-color") });
console.log(drugColor);
console.log(drugName);
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "SendDrugName.asmx/InsertDrugNameToDatabase",
data: drugName,
dataType: "json",
success: function (data) {
//response(data.d);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(thrownError);
}
});
}
});
});
</script>
<script type="text/javascript">
$(document).ready(function () {
$(".drugQuizzes").draggable({ tolerance: "fit" });
$(".drugAnswers").droppable({
drop: function (event, ui) {
var drugName = JSON.stringify({ "drugName": $(ui.draggable).find("span").text() });
var drugColor = JSON.stringify({ "drugColor": $(ui.draggable).css("background-color") });
console.log(drugColor);
console.log(drugName);
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "SendDrugName.asmx/InsertDrugNameToDatabase",
data: drugName,
dataType: "json",
success: function (data) {
//response(data.d);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(thrownError);
}
});
}
});
});
</script>
I have a version of the stored procedure ans JS where only one parameter is sent to the stored procedure, and that works.
From the console.log(drugName) and console.log(drugColor) I get
{"drugColor":"rgb(255, 69, 0)"}
{"drugName":"ORACEA"}
How can I make the data parameter of the ajax call take multiple parameters at once?
What are some names of general techniques that I need to be aware of for sending more than one parameter to a stored procedure at once using jQuery ajax?

Consider building an object literal on the client-side and passing that entire object to the service, thus you have one parameter in your service call, like this:
Client-side:
var myData = {};
myData.DrugName' = $(ui.draggable).find("span").text();
myData.DrugColor' = $(ui.draggable).css("background-color");
// Create a data transfer object (DTO) with the proper structure, which is what we will pass to the service.
var DTO = { 'theData' : myData };
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "SendDrugName.asmx/InsertDrugNameToDatabase",
data: JSON.stringify(DTO),
dataType: "json",
success: function (data) {
//response(data.d);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(thrownError);
}
});
Now on the service-side, you will need to build a class that represents the contents of the object literal created above, like this:
public class ServiceData
{
public string DrugName { get; set; }
public string DrugColor { get; set; }
}
Finally, change your web service code to accept one parameter, like this:
[WebMethod]
public void InsertDrugNameAndColorToDatabase(ServiceData theData)
{
string cs = ConfigurationManager.ConnectionStrings["dbcs"].ConnectionString;
using (var con = new SqlConnection(cs))
{
using (var cmd = new SqlCommand("spInsertDrugText", con))
{
con.Open();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("#drugName", theData.DrugName);
cmd.Parameters.AddWithValue("#drugColor", theData.DrugColor);
cmd.ExecuteNonQuery();
}
}
}
Note: The data passed from the jQuery call is automatically matched up with the class properties you have in your ServiceData class as long as the names match on both the client-side and server-side.

You can specify multiple data items like:
data: 'drugName='+ drugName + '&drugColor=' + drugColor;

You don't need to stringify it at all, you can pass the parameters as an object. Try this:
$(".drugAnswers").droppable({
drop: function (event, ui) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "SendDrugName.asmx/InsertDrugNameToDatabase",
data: {
'drugName': $(ui.draggable).find("span").text(),
'drugColor': $(ui.draggable).css("background-color")
},
dataType: "json",
success: function (data) {
//response(data.d);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr.status);
console.log(thrownError);
}
});
}
});
The ajax() function will then stringify it for you and pass it across to your C# endpoint.

but i get nothing.how to solve it.any one helps me is greatly appreciated.thanks in advance

just change the data and response in the ajax as given below
data: "{'PhoneContactName':'" + document.getElementById("<%= ContactName.ClientID %>").value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
in your case change the PhoneContactName as something like the tag etc.,
hope this helps :D

There are 2 things to take care here:
A- make sure that you can call your service method, use [WebMethod] attribute over your function to make it available to be called over http.
you may also need to tune the WebService settings a little to make it to work.
B- Your javascript code is too much for this task.
considering what is written inside the official documentation of Autocomplete, you only need to point out 2 things:
Url of the fetching method,
The control that the user is going to write on, and will trigger the
autocomplete call using the current value inside.
Consider the following example:
$(".tb").autocomplete({source: "URL_OF_YOUR_REMOTE_METHOD"});
considering your example, you will need to put this code:
$(".tb").autocomplete({source: "WebService.asmx/FetchTagList"});
This is the minimal piece of code that you need in order to make it to work.
but to take everything manually as you did, is a little bit complicated and not that easy to figure our problem once they start to happen.
a live example: http://jsfiddle.net/grtWe/1/
just use this piece of code and let me know if it works, then we may go from here to achieve your goal.

if FetchTagList is your webmethod you are calling from jquery then don`t return list from method you can bind datatable directly to the autocomplete textbox just check following link how to do that.
http://nareshkamuni.blogspot.in/2012/06/sample-example-of-jquery-autocomplete.html
also you can do that using ajax autocomplete extender. for using ajax autocomplete extender refer following link
http://www.aspsnippets.com/Articles/ASPNet-AJAX-AutoCompleteExtender-Pass-Additional-Parameter-to-WebMethod-using-ContextKey.aspx

script is as follows:
<script type="text/javascript">
$(document).ready(function () {
SearchText();
});
function SearchText() {
$(".auto").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Photos.aspx/GetAutoCompleteData",
data: "{'CategoryName':'" + document.getElementById("<%= txtCategory.ClientID %>").value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error Occurred");
}
});
}
});
}
</script>
web method:
[WebMethod]
public static List<string> GetAutoCompleteData(string CategoryName)
{
List<string> result = new List<string>();
OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\"|DataDirectory|\\ImageDB2.mdb\";Persist Security Info=True");
string query = "select TagName from TAGS where TagName LIKE '%" + CategoryName + "%'";
OleDbCommand cmd = new OleDbCommand(query, con);
con.Open();
//cmd.Parameters.Add("#ptext", System.Data.SqlDbType.NVarChar).Value = CategoryName;
OleDbDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
result.Add(dr["TagName"].ToString());
}
return result;
}

C# code
One thing need to remember here, Json data we cannot create manually, create using JavaScriptSerializer Class
<%# WebHandler Language="C#" Class="CountryStateCityHandler" %>
using System;
using System.Web;
using System.Data;
using System.Collections.Generic;

}
if (context.Request.QueryString["action"] == "getcountry")
{
DataTable dt = GetDataTable("EXEC PR_GetCountries"); //GetDataTable need to write, this method will call the Database and get the result
