ajax calls for checking existing email or name

Question

Hai all i wrote this for calling rmail is exists or not in my db

 

$(document).ready(function () {

function NameChecking() {

var name= $("#<%=TxtName.ClientID%>").value;

alert(name)

$.ajax({

type: "POST",

url: "Default.aspx/CheckEmail",

data: '{Name: "' + $("#<%=TxtName.ClientID%>")[0].value + '" }',

contentType: "application/json; charset=utf-8",

dataType: "json",

success: OnSuccess,

failure: function (response) {

alert(response);

}

});

 

}

  <asp:TextBox ID="TxtName" runat="server" onchange="NameChecking();" AutoPostBack="false" CausesValidation="True" ClientIDMode="Static"></asp:TextBox>

 

and mmy .cs file is

[System.Web.Services.WebMethod]

public static string CheckEmail(string Name)

{

string s = ConfigurationManager.ConnectionStrings["con"].ConnectionString;

string result = "";

SqlConnection con = new SqlConnection(s);

SqlCommand cmd = new SqlCommand("SP_CheckName", con);

cmd.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("@Name", Name);

con.Open();

SqlDataReader dr = cmd.ExecuteReader();

if (dr.HasRows)

{

result = "true";

}

else

{

result = "false";

}

return result;

 

but the method namechecking is not firing which is in textbox control

 

any leads..

 

TIA
