Question

Hi,

In my current project I am using MUI, Caliburn.Micro & Ninject. But I have some issues:

1) How can I show WarehouseProductCategoriesPageViewModel form ShellPageViewModel from code?

        public ShellPageViewModel()
        {
            // TODO: Instance of WarehouseProductCategoriesPageViewModel is created but View is not showed.
            ActivateItem(new WarehouseProductCategoriesPageViewModel());            
        }

2) How can I navigate to UpdateCategoryPageViewModel from WarehouseProductCategories?

    public class WarehouseProductCategoriesPageViewModel : Screen
    {       
        // TODO: How navigate to Update Categoy Page?       
        public void GoToUpdateCategoryPage()
        {
            // Some code...
            // Navigation to Update Category Page
        }
    }

P.S. All questions are written in code.

I'll be very thankful to somebody who can help me.

Best Regards,
Serhiy
