Sys.Services.ProfileService Class

Provides the client proxy class for the profile service.

Namespace: Sys.Services

Inherits: None

Members

Remarks

The ProfileService class provides script access to a user's profile information. It calls methods of the profile service through the same infrastructure used to call any other Web service method.

The Profile class is a singleton; it has only one instance that provides a global point of access. It is always available to your application and you do not have to instantiate it.

Example

Description

The following example shows how to use the ProfileService class to obtain profile information for the currently authenticated user. For more information, see Using Profile Information with Microsoft Ajax.

Code

// The OnClickLogin function is called when 
// the user clicks the Login button. 
// It calls the AuthenticationService.login to
// authenticates the user.
function OnClickLogin()

        document.form1.userPwd.value,false,null,null,
        OnLoginComplete, AuthenticationFailedCallback,
        "User context information.");
}


// The OnClickLogout function is called when 
// the user clicks the Logout button. 
// It logs out the current authenticated user.

        null, OnLogoutComplete, AuthenticationFailedCallback,null);

    // housekeeping goes here.

// authenticated. It loads the user's profile.
