Question

So let me put it this way.

I have a LogInViewModel and a LogInView. There is a Login() method in the ViewModel that gets called if the user clicks on a button in the View. Now I want the dashboard to show if the login was successful. How do I do this? I can’t find a clear answer to this in the documentation.

Answer 1

I assume that your dashboard is essentially your shell. In which case, you can bootstrap your LoginViewModel and in the Login method, after a successful login, you can show the DashboardViewModel and close the LoginViewModel using the Caliburn.Micro WindowManager.

Something like (using MEF):

Bootstrapper.cs

public class Bootstrapper : Caliburn.Micro.Bootstrapper<ILoginViewModel>
{
  ...
}

LoginViewModel.cs

public class LoginViewModel : Screen, ILoginViewModel
{
    private readonly IWindowManager windowManager;

    private readonly IDashboardViewModel dashboardViewModel;

    [ImportingConstructor]
    public LoginViewModel(IWindowManager windowManager, IDashboardViewModel dashboardViewModel)
    {
        this.windowManager = windowManager;
        this.dashboardViewModel = dashboardViewModel;
    }

    public void Login()
    {            
        // if login success...
        this.windowManager.ShowDialog(this.dashboardViewModel);
        this.TryClose();
    }
}
