Um, well, I'd do it like this if I wanted to just pass the status bar:

// RTDFile.cs

public partial class RTDFile {
  public StatusBar Status { get; set; }

  void SomeMethod()
  {
    Status.Push(0, String.Format("Downloading {0}", filename));
  }

}

// MainWindow.cs

public partial class MainWindow : Window {

  public MainWindow() {
    this.Build();

    this.File = new RTDFile();
    this.File.Status = this.Statusbar1;
  }
}

Or this if I wanted to use a delegate

// RTDFile.cs

public partial class RTDFile {
  public Action<uint,string> SetStatus { get; set; }

  void UpdateStatus( params string[] message ) {
    if ( SetStatus != null ){
      SetStatus( 0, String.Format( message ) );
    }
  }
  
  void SomeMethod() {
    SetStatus("Downloading {0}", filename);
  }
}

// MainWindow.cs

public partial class MainWindow : Window {

  public MainWindow() {
    this.Build();
    this.File = new RTDFile();
    this.File.SetStatus = SetStatus;
  }

  public void SetStatus( uint id, string message ) {
    this.Statusbar1.Push( id, message );
  }
}

Have Fun :)
