How to switch userControls in code?
   Reply    Contact

Hello

I have 2 user controls in my project : 1- authentification form - AuthForm and 2 - ChatForm

AuthForm user control has event UserAuthentificated.

How can i switch between these controls in code? I mean when user is authetificated then AuthForm control shold be replaced byChatForm

public partial class App : Application

{

    public App()

    {

        this.Startup += this.Application_Startup;

        this.Exit += this.Application_Exit;        this.UnhandledException += this.Application_UnhandledException;

        InitializeComponent();

    }

    private void Application_Startup(object sender, StartupEventArgs e)

    {

        var AuthForm = new AuthForm();

        this.RootVisual = AuthForm;

        AuthForm.UserAuthentificated += new UserAuthEventHandler(AuthForm_UserAuthentificated);

    }

    private void Application_Exit(object sender, EventArgs e){}

    private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e){}

    void AuthForm_UserAuthentificated(object sender, UserAuthEventArgs e)

    {

        var chatForm = new ChatForm();        this.RootVisual = chatForm;

    }

}

It doesn`t work

Kostja,

You could create a container control as your RootVisual and then let the container control orchestrate the display of the authentication and chat forms.

I tried this out and looked at the source for the RootVisual property. It goes off into some unmanaged code. I have however found a post from Pete Brown explaining it.

I suppose the general way you would have to do this would be to make some form of UserControl container class as was suggested above. I'm seeing if I can mock you one up quickly. If you beat me to it, post it here.
