# simple jquery callback works on .net3.5 but nothing fires on .net 2.0
i have the following jquery postback method on the client
<%@ Page [Language](https://www.mindstick.com/startup/28/preply-the-fast-growing-platform-transforming-language-learning)="C#" AutoEventWireup="true" CodeFile="CallServerWithParameters.aspx.cs" Inherits="CallServerWithParameters" %>
and the following [web method](https://www.mindstick.com/interview/746/how-do-you-invoke-a-web-method-of-web-service-in-ajax) on the [server side](https://www.mindstick.com/forum/318/how-to-call-javascript-fuction-in-server-side)
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
public [partial class](https://www.mindstick.com/forum/155717/define-partial-class-in-mvc) CallServerWithParameters : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static string GetAvailableTicketsForMales(int no)
{
[string result](https://www.mindstick.com/forum/12841/in-mvc-how-do-i-return-a-string-result) = "";
int NoOfTicketsAvailable = 5;
if (no > NoOfTicketsAvailable)
{
result = "Only " + NoOfTicketsAvailable.ToString() + " Male ticket(s) avaialable. Please eneter a lower number!";
}
return result;
}
}
problem is everything [works fine](https://answers.mindstick.com/qa/115732/my-software-works-fine-on-windows-10-but-crashes-on-windows-11-why) on .net 3.5 but if i use the same code on .net 2.0 the webmethod event does not get call at all, anybody have any idea what i did wrong?

Hi Ashish, try this:\
