                        transport: {
                            read: function (options) {
                                $.ajax({

    public static string GetEvents()
    {
        EventsOrg obj = new EventsOrg { FirstName = "Test", LastName = "11/22/1234", City = "tst", Age = "10" };
        List<EventsOrg> objEvent = new List<EventsOrg>();
        objEvent.Add(obj);
        EventsOrg obj1 = new EventsOrg { FirstName = "Test 1", LastName = "1/12/1993", City = "tst 1", Age = "10" };
        objEvent.Add(obj1);

        JavaScriptSerializer js = new JavaScriptSerializer();
        string strJSON = js.Serialize(objEvent);
        return strJSON;

        //  return new JavaScriptSerializer().Serialize(objEvent);

You don't have to serialize you collection into a JSON string since you have declared your GetEvents() function as a WebMethod.

Just return the list:

 public static List<EventsOrg> GetEvents()
    {
        EventsOrg obj = new EventsOrg { FirstName = "Test", LastName = "11/22/1234", City = "tst", Age = "10" };
        List<EventsOrg> objEvent = new List<EventsOrg>();
        objEvent.Add(obj);
        EventsOrg obj1 = new EventsOrg { FirstName = "Test 1", LastName = "1/12/1993", City = "tst 1", Age = "10" };
        objEvent.Add(obj1);

return objEvent;
}
