The link you posted doesn't work for me but if I am understanding you correctly you are looking for a way to run server side code from the client such as ajax or from silverlight using PageMethods.

You should take a look at /base: http://our.umbraco.org/wiki/reference/umbraco-base

It provides a super simple way of accessing server side code from the client.

Hi Slace & Max,

Thank you for your reply . Im not so sure if we can call authentication on the current settion when using Web Service, I assume its on an isolated session. But please correct me if I am mistaken.

I have this silverlight app that need authentication from Umbraco members. So to invoke this I have to call client Script  loginUser(username, password)  then pass it to page methods userlogin(string userName, string password).

To my understanding Im not so sure if I can Authenticate umbraco members via webservice? if that so perhaps I can use base or ASMX.

Thanks you guys in advance for the big help,

SILVERLIGHT CODE

    private void OKButton_Click(object sender, RoutedEventArgs e)

        {

            HtmlPage.Window.Invoke("loginUser", txtUserName.Text,  txtPassword.Password.ToString());

            this.DialogResult = true;

        }

ASPX PAGE

CLIENT SCRIPT

 <script type="text/javascript">

         function loginUser(username, password) {          

             PageMethods.userlogin(username, password, OnSucceeded);             

         }

         function OnSucceeded(result, userContext, methodName) {

             if (result) {

                 window.location = " <% =Request.Url.AbsoluteUri.ToString()  %>";
                          }

             else {

                window.location = " <% =Request.Url.AbsoluteUri.ToString()  %>";
             }   }

    </script>

CODE BEHIND

 [WebMethod, ScriptMethod]

        public static bool userlogin(string userName, string password)

        {

            Member m = Member.GetMemberFromLoginNameAndPassword(userName, password);           

            if (m != null)
            {                

                Member.AddMemberToCache(m,true, new TimeSpan(2, 0, 0));               

                return true;
            }

            return false;        

        }

I suggest you actually learn a bit more about AJAX and how MS AJAX works in regards to PageMethods and ASMX. 

A PageMethod is nothing more than a static method embedded in a class which inherits from System.Web.UI.Page and when you set it to static and have the ScriptMethod attribute.
When you include a ScriptManager the page response is processed and the ScriptMethods are detected, then JavaScript in injected (although with a client proxy method) to allow it to be invoked via JavaScript.

A PageMethod is actually called via 'MyPage.aspx/MyPageMethod'.

You can invoke this yourself with a framework like jQuery, but since it's just a URL you can swap it out into something like an ASMX or a WCF JSON service.

Here's a good post which covers how to use jQuery to call an ASMX: http://encosia.com/2008/03/27/using-jquery-to-consume-aspnet-json-web-services/

Also, keep in mind that a PageMethod doesn't actually have page scope. You can't (from the server) interact with controls, Session, Request, Response, etc all have to be accessed via the static property on HttpContext. And so on. All of this is also the same in an ASMX.

Hi slace ,

You are right with

so, keep in mind that a PageMethod doesn't actually have page scope. You can't (from the server) interact with controls, Session, Request, Response, etc all have to be accessed via the static property on HttpContext. And so on. All of this is also the same in an ASMX.

But it affect the Current Session specialy user identify on the sesssion. Do you think we can do this on ASMX? or WCF?

Notice

       Member m = Member.GetMemberFromLoginNameAndPassword(userName, password);           

            if (m != null)
            {                

                Member.AddMemberToCache(m,true, new TimeSpan(2, 0, 0));               

                return true;
            }

Well first off you shouldn't be interacting with the Membership API in Umbraco directly, unless you're working on a v3.0.x site as Umbraco 4 moved to the ASP.NET Membership Provider model - http://our.umbraco.org/wiki/how-tos/membership-providers

And session scope for a person on your website is maintained by a cookie which is sent to/ from the server, which is why when you use Session as a storage module it exists for just that user and only while they have their browser open to your site (and the session timeout hasn't been hit of course).

(Although using Session for storing data is a really bad idea anyway, but that's another topic all together)

This is a bit offtopic, but I've read the wiki about the membership provider, and it seems there are still some limitations. How can you acces the membertype of a member using the ASP.NET Membership Provider model and how can I access extra properties I added to a membertype? Currently I still do this by directly interacting with the Membership API of Umbraco. I've created a topic with problems I ran into using the ASP.NET Membership Provider model.

http://www.aaron-powell.com/blog/july-2009/umbraco-member-profiles.aspx 

That's how. Can be a problem if you've got 2 different membership profiles though, but that's a pure ASP.NET limitation, not an Umbraco one (and I did a reply to a question somewhere which did have a bit of a solution).

HI slace,

I found some sample for Membership and Silverlight.  Although you did not confirm if It can authenticate via Webservices, but in this example it can. I also mark your Reply as Solution.
