The way I would do it would be to make WizardWindow its own class.  Move
all the code that deals with it into that class and set up an event in
WizardWindow that will be raised when the user completes the assistant.
For example:

public class Window1
{
	[...]
	public void ShowWizard()
	{
		WizardWindow w =3D new WizardWindow();

		w.Finished +=3D new FinishedHandler(WizardFinishedCb);
		w.Show();
	}
=09
	private void WizardFinisihedCb(object o, EventArgs args)
	{
		// update tree view
	}
}

public delegate void FinishedHandler(object o, EventArgs args);

public class WizardWindow
{
	public event FinishedHandler Finished;

	public WizardWindow()
	{
		// Set up the window
	=09
		Button FinishButton =3D new Button("Finish");
		FinishButton.Clicked +=3D new
		     ButtonClickedEventHandler(FinishButtonClickedCb);
	}

	public void Show()
	{
		// Show the window
	}

	public void FinishButtonClickedCb(object o, EventArgs args)
	{
		// destroy the window
		window.Destroy();

		// raise the event
		if(Finished !=3D null)
			Finished(this, new EventArgs());
	}
}


Let me know if you need any clarification on this code.
