how to fix 'captcha validation is required' error in c#

After checking the i'm not a robot checkbox on validation, there's a java script alert "localhost:12345 says null" then when i click "OK" on the alert then go to click the submit button, still says "Captcha validation is required" even after i validated.
This is for my contact us page, validation won't work even after i got new keys which initially i thought were the problem.
C#
public partial class _default : System.Web.UI.Page
{
classes.Common xCommon = new classes.Common();
classes.Email xEmail = new classes.Email();
protected static string ReCaptcha_Key = "6LczL3QUAAAAAGnY8hnA-hgRjHV0q---------";
protected static string ReCaptcha_Secret = "6LczL3QUAAAAADWlVe0IKVERdq----------";
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_Contact_Submit_Click(object sender, EventArgs e)
{
xEmail.ContactUs_Email(txt_Contact_Name.Text, txt_Contact_Email.Text, txt_Contact_No.Text, ddl_Branch.SelectedItem.ToString(), ddl_Division.SelectedValue,ddl_Type.SelectedValue,txt_Contact_Message.Text, ddl_Branch.SelectedValue);
ltr_MessageReturn.Text = xCommon.Return_Message("contactus", "");
btn_Contact_Submit.Visible = false;
}
[WebMethod]
public static string VerifyCaptcha(string response)
{
string url = "https://www.google.com/recaptcha/api/siteverify?secret=" + ReCaptcha_Secret + "&response=" + response;
return (new WebClient()).DownloadString(url);
}
}
}
JavaScript
var onloadCallback = function () {
grecaptcha.render('dvCaptcha', {
'sitekey': '<%=ReCaptcha_Key %>',
'callback': function (response) {
$.ajax({
type: "POST",
url: "default.aspx/VerifyCaptcha",
data: "{response: '" + response + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (r) {
var captchaResponse = jQuery.parseJSON(r.d);
if (captchaResponse.success) {
$("[id*=txtCaptcha]").val(captchaResponse.success);
$("[id*=rfvCaptcha]").hide();
} else {
$("[id*=txtCaptcha]").val("");
$("[id*=rfvCaptcha]").show();
var error = captchaResponse["error-codes"][0];
$("[id*=rfvCaptcha]").html("RECaptcha error. " + error);
}
}
});
}
});
};
</script>
I expect the validation to pass after a user has selected all the required images to pass validation, and then submitted. but the output still says validation required.

Bind datatable with jQuery

I am trying to populate a datatable with data from SQL database. I have the following C# code which does return the correct number of records.
public class myClass
{
public int CenterID { get; set; }
public string CenterName { get; set; }
public string LicenseKey { get; set; }
public DateTime ExpiryDate { get; set; }
public string YearID { get; set; }
public DateTime Date { get; set; }
}
[WebMethod]
[System.Web.Script.Services.ScriptMethod(UseHttpGet = true)]
public static List<myClass> Bind()
{
SqlConnection con = new SqlConnection(
WebConfigurationManager.ConnectionStrings["MyDbConn"].ConnectionString);
con.Open();
List<myClass> newClass = new List<myClass>();
SqlDataReader rdr = null;
SqlCommand cmd = new SqlCommand("zCenterDetails_get", con);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
rdr = cmd.ExecuteReader();
while (rdr.Read())
{
newClass.Add(new myClass
{
CenterID = Convert.ToInt32(rdr["CenterID"]),
CenterName = rdr["CenterName"].ToString(),
LicenseKey = rdr["LicenseKey"].ToString(),
ExpiryDate = Convert.ToDateTime(rdr["ExpiryDate"]),
YearID = rdr["YearID"].ToString(),
Date = Convert.ToDateTime(rdr["Date"]),
});
}
con.Close();
return newClass;
}
The thing that I am struggling with is binding the data with AJAX. This is what I've tried so far but I know it is not correct. Please assist me to get my data into the datatable as I am new to datatables. Thanks
This is what I have so far:
function Bind() {
$.ajax({
type: "GET",
url: "WebForm1.aspx/Bind",
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (data) {
$('#datatable').DataTable({
data: data,
columns: [
{ 'data': 'CenterID' },
{ 'data': 'CenterName' },
{ 'data': 'LicenseKey' },
{ 'data': 'ExpiryDate' },
{ 'data': 'YearID' },
{ 'data': 'Date' }
]
});
}
});
}

ModelAndView("/authenticationError"); not working

after getting request from ajax to controller i am not able to move to next page through ModelAndView("/authenticationError.jsp");
controller code
#RequestMapping(value = "/ProcessReject,method = RequestMethod.POST" )
public ModelAndView Reject(#RequestParam(value = "StatusComments") String StatusComments,
#RequestParam(value = "ruleIndex") String ruleIndex,
#RequestParam(value = "country") String country,
HttpSession session) throws Exception {
ModelAndView mav ;
System.out.println("StatusComments "+ StatusComments);
System.out.println("ruleIndex "+ ruleIndex);
System.out.println("country "+ country);
String quicklookid = (String) session.getAttribute("quicklookid");
//rejectRuleBusinessLogic.reject(ruleIndex, country, quicklookid, StatusComments);
mav = new ModelAndView("/authenticationError.jsp");
return mav;
Ajax code
function showRejectStatusMsg(value1, value2)
{
$.ajax({
type: "POST",
cache: false,
url: "ProcessViewRule.ncr",
data:"ruleIndex=" +value1 +"&country="+value2,
success: function(response) {
},
error : function(e) {
alert('Error in response...' + e);
}
});
jsp code -
<a href="javascript:showRejectStatusMsg(<c:out value='${List.ruleindex}'/>, '<c:out value="${List.country}"/>')" id="rejectLink" class="navlink" >Reject</a>))

You are doing it wrong..You need to write .jsp and can set the view as
mav.setViewName("list");
Basically
new ModelAndView("welcomePage", "WelcomeMessage", message);
is shorthand for
ModelAndView mav = new ModelAndView();
mav.setViewName("welcomePage");
mav.addObject("WelcomeMessage", message);

My jquery ajax call is not working when I call web services which retrieves data from database

I am new working with jquery ajax calls in fact my first time and, I am running into a issue here my web service is working but for some reason when I try to call it from jquery ajax the data is not retrieve.
Please I've been working the whole day on this and I need to finish it tonight.
My web method is this :
public Didyoumean SayHello(string search)
{
Didyoumean Didyoumean = new Didyoumean();
string cs = ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString;
using(SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand ("USP_DidYouMean",con);
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter parameter = new SqlParameter("#search",search);
cmd.Parameters.Add(parameter);
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
Didyoumean.SearchInput = reader["detail"].ToString();
}
reader.Close();
con.Close();
}
return Didyoumean;
}
my Didyoumean class is this:
public class Didyoumean
{
public string SearchInput { get; set; }
}
my ajax call is this (the error is most likely to be here)
function bla() {
var SearchInput = document.getElementById("#locationSearchInput").value;
var DataObject = { search: SearchInput };
$.ajax({
type: "POST",
url: "/kiosk/EmailCoupon.asmx/SayHello",
data: JSON.stringify({dataObject}),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
$('.tags_select a').html(data.d);
},
error: function () {
$('.tags_select a').html("<p>no suggestion</p>")
}
});
}
and finally my html
<input id="Button1" type="button" value="button" onclick="bla()"/>
<div class="tags_select">
Basically what I am trying to do is depending on the data in my database the application give suggestions for spelling errors.
note: do not pay attention to the name of the functions and methods this is just a test.

Your service might be like this
[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
[WebMethod]
public Didyoumean SayHello(string search)
{
Didyoumean didyoumean = new Didyoumean();
didyoumean.searchInput = "result of " + search;
return didyoumean;
}
}
and your javascript is
function test() {
var SearchInput = "test";
$.ajax({
type: "POST",
url: "/WebService1.asmx/SayHello",
data: JSON.stringify({search:SearchInput}),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
var didYouMean = data.d;
alert(didYouMean.searchInput);
},
error: function (e) {
console.log(e);
}
});
}
