Can somebody tell me why WebMethod is not firing in one page alone, this same code works in another page, but not in the page which i want it to work. I shifted this entire code into a new page and it works perfectly fine there, but if i use it in my actual page, it doesn't fire the webmethod. Not sure what's happening.

Can you please check few things
1) check if you are able to call the api using rest api testing tools like postman
2) If you are able to access it can you please check if web developer tool console if it has any error like 404(Not found) or 500(Internal server error)
3) Modify your
data: "{ 'prefix': '" + request.term + "'}",
to
data: JSON.stringify({ prefix: request.term }),
Please check value of '<% =ResolveUrl("HRMCareerEAF.aspx/GetSkills") %>'
Also I am not sure but try getting rid of (EnableSession = true).
Thank you soo much for the support.
I found out the problem and solution.
Actual problem is that auto complete doesn't work after partial page postback and my txtskill is in 3rd view of asp:multiview which refreshes only the part of page inside my updatepanel.
Jquery methods do not bind if the page postbacks partially. I got solution in the following link.
Jquery Auto complete extender not working after postback
My altered code is as follows.
<script type="text/javascript">
$(function () {
SetAutoComplete();
});
$(document).ready(function () {
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(InitializeRequest);
prm.add_endRequest(EndRequest);
// Place here the first init of the autocomplete
SetAutoComplete();
});
function InitializeRequest(sender, args) {
}
function EndRequest(sender, args) {
// after update occur on UpdatePanel re-init the Autocomplete
SetAutoComplete();
}
function SetAutoComplete() {
$("[id$=txtSkill]").autocomplete({
source: function (request, response) {
$.ajax({
url: '<% =ResolveUrl("HRMCareerEAF.aspx/GetSkills") %>',
data: JSON.stringify({ prefix: request.term }),

I have a autocomplete in a grid-view in a ascx file but the autocomplete is not working in the ascx file. I have made several similar autocomplete in other page that work. Why is it that the autocomplete does not work in my ascx file. I have a hypotheses why it does not work but I am unsure how to fix it here it is
I think that the problem is with the following url in the javascript
url: "contratoGerencia.aspx/getSupplierAndComponente"
However I dont know how I should change it don get it to work with the ascx file.Also I found a solution here https://www.codeproject.com/Questions/757769/How-to-Call-Ascx-page-form-JavaScript-Funnction-Of that is almost what I want the only problem is that I also have a textbox in my situation.
Any help would be very appreciated. I hope the following information will help you.
Here is my ascx (ComponentesControler.ascx) code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<link href="../css/autocomplete.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="../scripts/autocomplete.js" ></script>
<asp:TextBox CssClass="gridContractAndComponente" ID="txtContractComponenteFooter" Text="" runat="server" TextMode="MultiLine" Rows="1" />
Here is my ascx.cs (ComponentesControler.ascx.cs) code
[WebMethod]
public static List<string> getSupplierAndComponente(string prefixText)
{
string lv_numero_contrato;
List<string> numeros_contrato = new List<string>();
connectionStringBuilder builder = new connectionStringBuilder();
String connString;
connString = builder.builder.ConnectionString;
string selectStatement = " SELECT numero_contrato FROM erp_contratos ";
using (MySqlConnection conn = new MySql.Data.MySqlClient.MySqlConnection(connString))
{
conn.Open();
using (MySqlCommand cmd = conn.CreateCommand())
{
cmd.CommandText = selectStatement;
cmd.Parameters.AddWithValue("#searchText", prefixText);
using (MySqlDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
lv_numero_contrato = reader.GetString(reader.GetOrdinal("numero_contrato"));
numeros_contrato.Add(lv_numero_contrato);
}
}
conn.Close();
}
}
return numeros_contrato;
}
Here is the aspx page (contratoGerencia.aspx) were I use the ascx file
<div id="ComponentesSection" class="menusection">
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Always" >
<ContentTemplate>
<TWebControl5:WebControl5 ID="Header8" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
Here is my javascript file (autocomplete.js)
$(document).ready(function () {
SearchSupplierAndComponente();
});
function SearchSupplierAndComponente() {
$(".gridContractAndComponente").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "contratoGerencia.aspx/getSupplierAndComponente",
data: "{'containedText':'" + document.getElementById('PageContent_gvPrimaryGrid_txtContractComponenteFooter').value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}
The problem is in the name of your parameter entered in AJAX, your method expects to receive a parameter named prefixText and not containedText.
Change
data: {'containedText':'" + document.getElementById('PageContent_gvPrimaryGrid_txtContractComponenteFooter').value + "'}
with
data: {'prefixText':'" + document.getElementById('PageContent_gvPrimaryGrid_txtContractComponenteFooter').value + "'}
The issue can be triggered by the UpdatePanel like explained here:
jQuery $(document).ready and UpdatePanels?
So modify your autocomplete.js like this:
$(document).ready(function() {
SearchSupplierAndComponente();
});
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {
SearchSupplierAndComponente();
});
function SearchSupplierAndComponente() {
$(".gridContractAndComponente").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "contratoGerencia.aspx/getSupplierAndComponente",
data: "{'containedText':'" + document.getElementById('PageContent_gvPrimaryGrid_txtContractComponenteFooter').value + "'}",
dataType: "json",
success: function (data) {
response(data.d);
},
error: function (result) {
alert("Error");
}
});
}
});
}
See if the console error goes away.
I have this function using the jquery autocomplete widget, that I am getting the following error:0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'autocomplete'
On my html page, in the head section I have included the following tags.
<script src="Scripts/jquery-1.10.2.min.js"></script>
<script src="Scripts/jquery-ui-1.11.4.min.js"></script>
The function is called by a variety of option button calls to do several different query's. I have this function in a different application that works well but here it is not.
function AutoComplete(Type) {
//create AutoComplete UI component
$("#txtCriteria").autocomplete({
source: function (request, response) {
$.ajax({
autoFocus: true,
async: false,
delay: 250,
url: "wsReports.asmx/AutoComplete",
data: "{'Type':'" + Type + "', 'filter':'" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
label: item.ACName,
value: item.ACCode
} // end of return
})) // end of response
} // end of success
}); // end of ajax
}, // end of source
select: function (event, ui) {
if (ui.item.value == "") {
alert("nothing to select");
}
else {
// prevent autocomplete from updating the textbox
event.preventDefault();
// manually update the textbox and hidden field
$(this).val(ui.item.label);
}
}, // end of select
change: function (event, ui) {
if (!ui.item) {
$(event.target).val('');
}
},
}) // end of txtCriteria.autocomplete
} // end of AutoComplete
Any ideas why it is not recognized in the above situation?
My fault. The jquery.js and bootstrap were loading after the jquery-ui.
I'm using asp.net webservice to use it in jQuery UI autocomplete plugin and here is the data I'm getting.
{"d":[
{
"__type":"WebS.Model.SearchModel",
"MainCommodityId":1,
"MainCommodityName":"Pulses",
"SubcommodityId":3,
"SubCommodityName":"Urid Dal",
"BrandId":3,
"BrandName":"President"
},
{
"__type":"WebS.Model.SearchModel",
"MainCommodityId":1,
"MainCommodityName":"Pulses",
"SubcommodityId":1,
"SubCommodityName":"Red Gram",
"BrandId":4,
"BrandName":"President"
}
]
}
This is the script I'm using:
$(document).ready(function () {
$(".input-search").autocomplete({
source: function (request, response) {
$.ajax({
url: '/WebServices/GetAllBrandNames.asmx/getAllBrands',
data: "{ 'data': '" + request.term + "'}",
dataType: "json",
contentType: "application/json; charset=utf-8",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item.BrandName,
label: item.SubCommodityName
}
}))
},
error: function (response) {
alert('error');
},
failure: function (response) {
alert('faii');
}
});
},
select: function (e, i) {
console.log(i.MainCommodityId);
console.log(i.SubcommodityId);
console.log(i.BrandId);
},
minLength: 1
}).autocomplete("instance")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + "" + item.BrandName + " in " + item.MainCommodityName + " - " + item.SubCommodityName + "</a>")
.appendTo(ul);
};
});
The issues are:
When I tried to enter keyword say: pre the aforesaid output is coming in json. However, the list is returning only one "President" item where it should display 2 items.
The list is displaying "undefined in undefined - undefined" instead of values after adding .autocomplete("instance")._renderItem function.
console.logs are also undefined after selecting an item.
How can these issues fixed?
The default behavior of the select event is to update the input with ui.item.value. This code runs after your event handler.
Simply prevent the default action on select and focus using event.preventDefault() or by return false and use _renderItem for custom dropdown.
focus: function(event, ui) {
// prevent autocomplete from updating the textbox
event.preventDefault(); // or return false;
}
select: function(event, ui) {
// prevent autocomplete from updating the textbox
event.preventDefault();
//do something
}

Finally, I was able to achieve what I wanted. Answering my question as it may helpful to someone.
javascript:
$(document).ready(function () {
$(".input-search").autocomplete({
source: function (request, response) {
$.ajax({
url: '/WebServices/GetAllBrandNames.asmx/getAllBrands',
data: "{ 'data': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (data) {
response($.map(data.d, function (item) {
// don't forget to $.map to (data.d where d is the top node
return {
// assign values from json response for further use
brandid: item.BrandId,
brand: item.BrandName,
maincommodityid: item.MainCommodityId,
maincommodity: item.MainCommodityName,
subcommodityid: item.SubcommodityId,
subcommodity: item.SubCommodityName
}
}));
},
error: function (response) {
alert('Server Error. Please try again.');
},
failure: function (response) {
alert('Failed to get result');
}
});
},
focus: function (event, ui) {
// prevent autocomplete from updating the textbox
event.preventDefault();
},
select: function (event, ui) {
// prevent autocomplete from updating the textbox
event.preventDefault();
// do further action here such as assigning id to hidden field etc.
$(".input-search").val(ui.item.brand);
// navigate to the selected item's url ex: /catalogue/1/1/pulses/red-gram/4/president
var str = "/catalogue/" + ui.item.maincommodityid + "/" +
ui.item.subcommodityid + "/" + $.trim(ui.item.maincommodity.replace(/\s+/g, '-').toLowerCase()) + "/" +
$.trim(ui.item.subcommodity.replace(/\s+/g, '-').toLowerCase()) + "/" + ui.item.brandid + "/" +
$.trim(ui.item.brand.replace(/\s+/g, '-').toLowerCase());
window.location = str;
},
minLength: 3
}).autocomplete("instance")._renderItem = function (ul, item) {
// get values and create custom display
var $a = $("<a></a>");
$("<strong></strong>").text(item.brand).appendTo($a);
$("<span></span>").text(" in ").appendTo($a);
$("<span></span>").text(item.subcommodity).appendTo($a);
return $("<li></li>").append($a).appendTo(ul);
};
});
CSS:
ul.ui-front {
z-index: 1200; // change z-index according to your UI.
}
Usually I do this way and Its work.
$(document).ready(function () {
var jsondata=array();
$.post("/WebServices/GetAllBrandNames.asmx/getAllBrands",{data: request.term},function(data){
var data=JSON.parse(data);
$.each(data.d, function( index, value ) {
jsondata[index].value=value;
});
$(".input-search").autocomplete({
source:jsondata,
//other property and events
})
});
I mean apply source JSON after completing request because sometimes if AJAX takes some time to load execution pointer still execute rest of code without waiting for response.
I did not test this code but I always do this way and never get your kind of error. Good Luck
Please help. I'm using MVC, razor 3, jquery.
I dynamically create a multi select box when a dropdown selection changes. I bind the multiple selection to a List in my model. And it works, except it passes me the list of selected indice, instead of a list of the selected text. I want selected text, not index of the list. I set the value as text, but I have no luck.
if I manually create the list, everything works. How do I pass a list of selected options back to the controller?
I have this div in my view:
<div class="row-fluid" id="divAvailableAssemblies" hidden ="hidden">
<label class="span4">Available Assemblies:</label>
<select multiple="multiple" class="span8 ui-corner-all" id="Request_SelectingAssemblies" name="Request.SelectingAssemblies">
#*<option value="test">test</option>
<option value="test2">test2</option>*#
</select>
</div>
Here my jquery:
<script type="text/javascript">
$(function () {
$('#ddPartsToCreate').live('change',function () {
var selectedPart = this.value;
if (selectedPart < 6 || $("#txtOrderNumber").val()=="")
{
$("#divAvailableAssemblies").attr("hidden", "hidden");
return;
}
$("#divAvailableAssemblies").removeAttr("hidden");
$.ajax({
type: 'POST',
url: '#Url.Action("GetSelectingAssembliesFromOrder", "Home")',
data: JSON.stringify({ orderNumber: $("#txtOrderNumber").val() }),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
cache: false,
async: false,
success: function (response) {
var returnedData = JSON.parse(response);
var selectingAssemblies = $("#Request_SelectingAssemblies");
selectingAssemblies.empty();
for (var assembly in returnedData)
{
//selectingAssemblies.append($('<option >', { value: assembly }).text(returnedData[assembly].Text)).hide().show();
//selectingAssemblies.append($('<option value=' + assembly + '>' + returnedData[assembly].Text + '</option>'));
//selectingAssemblies.append($('<option >', { value: assembly, text: returnedData[assembly].Text }));
//selectingAssemblies.append($('<option></option>').val(assembly).html(returnedData[assembly].Text));
//$("#Request_SelectingAssemblies").append($('<option>', { value: assembly }).text(returnedData[assembly].Text));
//$("#Request_SelectingAssemblies").append($('<option>', { value: assembly }).text(returnedData[assembly].Text));
//$('<option />', { value: assembly, text: returnedData[assembly].Text }).appendTo(selectingAssemblies);
selectingAssemblies.append($('<option></option>').val(assembly).html(returnedData[assembly].Text));
}
},
error: function (jqXHR, textStatus, errorThrown) {
alert(errorThrown);
}
});
});
});
in the backend, I generate JSON:
foreach (var assembly in pr.ShipParts)
{
sb.Append(String.Format(",{{\"Text\":\"{0}\", \"Value\":\"{1}\"}}", assembly.Mark.ToString(), assembly.Mark.ToString()));
availableAssemblies.Add(assembly.Mark.ToString());
}
I bind the multiple selection(Request_SelectingAssemblies) with this property in my model:
public List<String> SelectingAssemblies
{
get
{
return _SelectingAssemblies;
}
set
{
_SelectingAssemblies = value;
}
}
private List<String> _SelectingAssemblies = new List<string>();
When it gets to my action in the controller, SelectingAssemblies has index instead of the actual text. But I set the value of each option as text. If I set the option manually, they will show in source page and return the text. But since I dynamically create the options, they don't show in source page. I don't know how I can make MVC understand dynamic data.
In the picture, the list of CX001, RBX001, RBX002 is dynamically created. if I hit F12 in IE, I will see them created correctly in the DOM. If I choose CX001 and RBX002, SelectionAssembies will have 0 and 2.
Thanks

I am trying to fetch company name in textbox as autocomplete. When I run my project, Ajax will call the success function, and the record is also fetched correctly, but there are no autocomplete suggestions in the textbox.
My view is:
$("#idcompanyname").autocomplete({
source: function (request, response) {
var customer = new Array();
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: '#Url.Action("Companymap", "admin")',
data: "{'term':'" + document.getElementById('idcompanyname').value + "'}",
dataType: "json",
success: function (data) {
alert(data)
response($.map(data, function (v, i) {
var text = v.vcCompanyName;
alet(text)
if (text && (!request.term || matcher.test(text))) {
return {
label: v.vcCompanyName,
value: v.kCompanyId
};
}
}));
},
error: function(result) {
alert("No Match");
}
});
}
});
}
Here is Method on controller:
var query = db.tbaccounts.Where(t => t.vcCompanyName.ToLower()
.StartsWith(term)).ToList();
List<string> lst = new List<string>();
foreach (var item in query)
{
lst.Add(item.vcCompanyName);
}
return Json(lst, JsonRequestBehavior.AllowGet);
