Question

By default when you use \"ActivateItem(new Control());\" your control is loaded into a ContentControl which with the name ActiveItem, fro example. . If I have multiple conte

This is an old question, but in case anyone is having the same issue, here is my solution:

1. Your main window that contain both (or even more than two) of your User Controls must be inherited from Caliburn.Micro.Conductor.Collection.AllActive;
2. Your User Controls must be inherited from Caliburn.Micro.Screen;
3. You must also keep naming conventions in mind. If you use MenuUC as the name of a ContentControl in your View, also create a property named MenuUC in your ViewModel;
4. Initialize your UserControl as I do in Constructor;
5. Now you can use ActivateItem(MenuUC) and DeactivateItem(MenuUC) everywhere in your code. Caliburn.Micro automatically detects which one you want to work with.

Example XAML View code:

Example C# ViewModel code:

class YourViewModel : Conductor.Collection.AllActive
{
    // Menu Side Bar
    private MenuUCViewModel _menuUC;
    public MenuUCViewModel MenuUC
    {
        get { return _menuUC; }
        set { _menuUC = value; NotifyOfPropertyChange(() => MenuUC); }
    }

    // Panel
    private Screen _panelUC;
    public Screen PanelUC
    {
        get { return _panelUC; }
        set { _panelUC = value; NotifyOfPropertyChange(() => PanelUC); }
    }

    // Constructor
    public YourViewModel()
    {
        MenuUC = new MenuUCViewModel();
        ActivateItem(MenuUC);

        PanelUC = new FirstPanelUCViewModel();
        ActivateItem(PanelUC);
    }

    // Some method that changes PanelUC (previously FirstPanelUCViewModel) to SecondPanelUCViewModel
    public void ChangePanels()
    {
        DeactivateItem(PanelUC);
        PanelUC = new SecondPanelUCViewModel();
        ActivateItem(PanelUC);
    }
}

In the above example, ChangePanels() acts as a method to load new User Control into your ContentControl.
