Hi all,

I'm implementing a web site in which forms authentication and membership profile is used. I don't use a separate login page but a popup div panel that uses ajax authentication underneath.

Everyting is fine but Sys.Services.AuthenticationService.logout() function of ajax makes a full post back. Is it supposed to in that way ? I think something is wrong with it.

Here are code snippet that I use:

Markup:

<a id="linkLogout" style="cursor:pointer;" onclick="return Logout();">Exit</a>

JavaScript:

function Logout()
        {
            // alert('Logout method invoked !');
            Sys.Services.AuthenticationService.logout(null, onLogoutCompleted, null, '');
            //AuthenticationStatus();
            return false;
        }

No metter what I'm doing, after Sys.Services.AuthenticationService.logout is invoked, it makes a post back.

Do you have any sugession to prevent it form posting back the page ?

Thanx for any help.

Hi BossDida,

I recommend that you have a look at the documentation of the authentication service class here:

http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.Services/AuthenticationServiceClass/default.aspx

There is also a useful sample inside. I believe it is helpful for you.

Best regards,
