使用WCF RIA在SilverLight中实现登录

Question

I create a login page with SilverLight. But when users log in and then refresh page, the user is logged out! In other words, the SilverLight application restarts. How can I prevent this from happening on refresh?

I had also the same problem and after that I found some thing like this.

I create two pages With Login page and Dashboard Page.Here is the my Login page code. this will help you.

    private void BtnLogin_Click(object sender, RoutedEventArgs e)
    {
        user.Username = TxtUsername.Text;
        user.Password = TxtPassword.Password;

        YourReference.YourReferenceServiceClient Service = new YourReferenceServiceClient();
        Service.LoginCompleted += Service_LoginCompleted;
        Service.LoginAsync(user);
    }

    void Service_LoginCompleted(object sender, LoginCompletedEventArgs e)
    {
        if (e.Result == true)
        {
            Dashboard UserDashboard = new Dashboard(user);
            this.Content = UserDashboard;
        }
        else
        {
            MessageBox.Show("Error Occured");
        }
    }

In WCF RIA service I created a method named as Login, Here is that code.

public bool Login(User LogUser)
{
    bool Status = false;

    //......Your Code.... if it is success return True otherwise false//

    return Status;
}
