    private MessageBoxResult isBlaBlaa()
    {
        Window w = new Window();
        w.Tag = MessageBoxResult.Cancel;

        Grid grid = new Grid();
        grid.Margin = new Thickness(30);

        grid.Children.Add(new TextBlock()
        {
            Text = "Bla blaa",
            Margin = new Thickness(0, 0, 0, 20)
        });

        Button btn;
        btn = new Button()
        {
            VerticalAlignment = System.Windows.VerticalAlignment.Bottom,
            HorizontalAlignment = System.Windows.HorizontalAlignment.Left,
            Content = "Cancel",
            Width = 100,
            Height = 30,

        };
        btn.Click += new RoutedEventHandler((object sender, RoutedEventArgs e) => { w.Tag = MessageBoxResult.Cancel; w.DialogResult = false; });
        grid.Children.Add(btn);

        btn = new Button()
        {
            VerticalAlignment = System.Windows.VerticalAlignment.Bottom,
            HorizontalAlignment = System.Windows.HorizontalAlignment.Center,
            Content = "No",
            Width = 100,
            Height = 30,

        };
        btn.Click += new RoutedEventHandler((object sender, RoutedEventArgs e) => { w.Tag = MessageBoxResult.No; w.DialogResult = false; });
        grid.Children.Add(btn);

        btn = new Button()
        {
            VerticalAlignment = System.Windows.VerticalAlignment.Bottom,
            HorizontalAlignment = System.Windows.HorizontalAlignment.Right,
            Content = "Yes",
            Width = 100,
            Height = 30,

        };
        btn.Click += new RoutedEventHandler((object sender, RoutedEventArgs e) => { w.Tag = MessageBoxResult.Yes; w.DialogResult = true; });
        grid.Children.Add(btn);


        w.Content = grid;

        w.ShowDialog();

        return (MessageBoxResult)w.Tag;
    }

Not sure I understand the problem but in WPF Window.DialogResult is bool? which means it can be either true, false or null, depending of what is the outcome. If you want to close WPF Window with success you need to set DialogResult to true. When you have Button.IsDefault = "true" then it will trigger click event on ENTER but won't close the dialog for you until DialogResult is set. 

private void btnOK_Click(object sender, System.EventArgs e)
{ 
   if (EnterNewSettings()) DialogResult = true;
}

and your DialogResult is passed as a result of Window.ShowDialog()

if (myDlg.ShowDialog() == true) ....

When you have Button.IsCancel = "true" then, on ESC, it will trigger click event and automatically close dialog with DialogResult=False

You have to implement the logic to confirm and close your messagebox your self.

Create a Public Property Succes

Public bool Success {get;set;}

And have this implementation in your ok button if you can to close your form and have it succeed: 

private void btnOK_Click(object sender, System.EventArgs e)
{ 
   if (!EnterNewSettings()){
   MessageBoxResult result = MessageBoxResult.None;
   }else{
      Success = true;
      Close();
   }
}

Then you can Check on the property Success

Could be i'm missing some syntax but i hope you get where it's going to :)
