How to preserve the full state of the View when navigating between Views in an MVVM application?

Question

I have an MVVM application that requires basic backward/forward navigation between screens. Currently, I have implemented this using a WorkspaceHostViewModel that tracks the

I have managed to fix it without using TabControlEx (cause it didn't work for me either). I've used Datatemplates and templateselector in order to switch between tabs.

Xaml:

The DataTemplateSelector:

 public class MainTabViewDataTemplateSelector : DataTemplateSelector
{
    public override DataTemplate SelectTemplate(object item, DependencyObject container)
    {
        FrameworkElement element = container as FrameworkElement;
        switch ((item as TabInfoEntity).TabIndex)
        {
            case 1:
                {
                    return element.FindResource("Dashboard") as DataTemplate;
                }
            case 2:
                {
                    return element.FindResource("SystemHealth") as DataTemplate;
                }

        }
        return null;
    }
}

TabInfoEntity class (list of objects of this type are the itemsource of the TabControl):

public class TabInfoEntity { public TabInfoEntity() {

    }
    private string name;

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    private int tabindex;

    public int TabIndex
    {
        get { return tabindex; }
        set { tabindex = value; }
    }
}
