I have a class to deal with session variables. Here is a sample attached:

namespace General

{



    public class Session

    {

        public Session()

        {

        }





        public static string UserID

        {

            get { return HttpContext.Current.Session[UserID] as string ?? String.Empty; }

            set { HttpContext.Current.Session[UserID] = value;  }

        }



        public static string departFlightID

        {

            get { return HttpContext.Current.Session[departFlightID] as string ?? String.Empty; }

            set { HttpContext.Current.Session[departFlightID] = value; }

        }



        public static string returnFlightID

        {

            get { return HttpContext.Current.Session[returnFlightID] as string ?? String.Empty; }

            set { HttpContext.Current.Session[returnFlightID] = value; }

        }

}



}

Now at some point I store the flightID in:

General.Session.departFlightID = flightID;

And at another point I want to retrieve this value using Javascript. I have seen examples here but they won't work (there's no error but they will return EMPTY).

Most recent tries:

 var session = '<%= General.Session.departFlightID %>';

 var session = '<%= HttpContext.Current.Session[departFlightID] %>';

It does work if I set value on page load, but I am running a webmethod where I create a html and then send that html back to be populated inside a div to make a ticket there. I need to get the session value but it does not update.

To make it more clear here is the Javascript code:

<script type=text/javascript>





function addTicket(flightID, flightType) {

    PageMethods.addTicket(flightID, flightType, OnGetMessageSuccess);

}



function OnGetMessageSuccess(result, userContext, methodName) {



    var pageUrl = document.URL;

    if (pageUrl.indexOf(&ret_date=&) !== -1) {



        var session = '<%= HttpContext.Current.Session[departFlightID] %>';



        alert(session);

        result = result + <a onclick=searchflight.abortAllAjax() data-index=6 class=bookNow title=Book Now! href=#>Book Now!</a>;

        result = result + </div>    </div>  </div>;

        document.getElementById(detail).innerHTML = result;

    }



}

And here is the webmethod:

[System.Web.Services.WebMethod]

    public static string addTicket(string flightID, string flightType)

    {

        //GET FLIGHT DETAILS  FROM DATATABLE OR SESSION DATA TABLE

        string tmpHtml = string.Empty;

        tmphtml=sample;

        string flightID=123123213;

        General.Session.departFlightID=flightID;



    return tmphtml;

    }
