Solution 1

I guess the scenario here is that he has a Window with a frame and the navigation method is also in this window.

What you can do is to pass your window to those dynamically created pages.

//Main Window
public class MainWindow
{
   public void NavigatePage(Page page)
   {
      YourFrameInstance.Navigate(page)
   }
 }

//Your Page
public class Page
{
    private readonly Window _mainWindow;

    public Page(Window mainWindow)
    {
       _mainWindow = mainWindow;
    }

    void Button_Click(object sender, RoutedEventArgs e)
    {
        var page = new Page(_mainWindow);
        _mainWindow.NavigatePage(page);
    }
 }

If I understand correctly, you want to navigate from one page to another using a event?

If that is the case, take a look at the following links below - these will give you a better understanding of navigating through a WPF application providing examples and sample apps.

How to Build, Manage and Navigate the User Interface of a WPF Application

Simple Navigation

This is how I achieve it. In the code behind of your application, do something like this to help navigate to the next page for your click event;

private void btnClick_HomeClick(object sender, RoutedEventArgs e)
{
     FrameContent.Navigate(new ExampleView()); //FrameContent is the name given to the frame within the xaml.
}

Hope this helps!

Sorry, I don't really understand what you're trying to say. I recommend you go through those two links I suggested or try and implement the code snippet I created for you. If I understand you correctly, you have multiple pages you want to navigate to. If thats the case, you could use a Menu or a Ribbon and use events to navigate through each page. Hope this helps.

Want to point out, that depending on what is on the page and how often you call for navigation, this can cause a memory leak as you are creating new instances of that class for each navigation without disposing of it. I like to use new Uri("ExampleView.xaml", UriKind.Relative) more because it seems to clean up after itself.
