Sharepoint Silverlight Form Based Authentication

[Dharmesh Trivedi]

I confess this is not a telerik issue however I am running into problem using e.g. Telerik Bookcontrol and populating with sharepoint List.and Form based Authentication.

I get following error when I try to assign list cookiecontainer to authentication.asmx cookie container ...

Message: Unhandled Error in Silverlight Application Unable to set the CookieContainer. Please make sure the binding contains an HttpCookieContainerBindingElement.   at CompanySilverlightApplication.AuthenticationService.AuthenticationServiceClient.set_CookieContainer(CookieContainer value)
   at CompanySilverlightApplication.News.News_Loaded(Object sender, RoutedEventArgs e)
   at System.Windows.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)
Line: 1
Char: 1

Hello Dharmesh,

If you are not using the client stack, can you please switch to it and see if it helps?

I too am having the same issue. I know this isn't a telerik issue, but I want to create a photoviewer for silverlight. Here is what i have tried so far. CookieContainer is still null on the AuthenticationSoapClient object...

   HttpWebRequest.RegisterPrefix("http://", WebRequestCreator.ClientHttp);

            

            AuthenticationSoapClient client = new AuthenticationSoapClient();

            (client.Endpoint.Binding as BasicHttpBinding).EnableHttpCookieContainer = true; //not sure if this is the right way to use this.      

            

            client.LoginCompleted += (o, e) =>

            {

                //Get the cookie

                if (e.Result.ErrorCode == LoginErrorCode.NoError)

                {

//client.CookieContainer IS NULL HERE.

                }

                else

                {

                    //BUMMER!

                }

            };

            client.LoginAsync("userid", "password");

No need to do what you describing if you creating Silverlight webpart hosted inside the sharepoint...

Do following and it works for me
(1) Copy ClientBin directory (which includes your XAP file) to the 12 \.... \ControlTemplates\ClientBin
(2) Make sure you give execute script permission to  ClientBin   in IIS
(3) make sure if you do refer the fba site web services
(4)make sure your webpart pointing at the location 12 \.... \ControlTemplates\ClientBin\abc.xap

let me know if you run into any other problem.
