Answer 1

Don't set the DataContext explicitly, or only via another Binding. Your

does nothing helpful. DataContext will be inherited as long as it is not overwritten. Don't set it explicitly. It should be enought to set it once on both windows.

Create your data object in your MainWindow

Texto prueba = new Texto("Carlos");
Window1 nueva = new Window1();
nueva.DataContext = prueba;
nueva.Show();

and remove all the other DataContext assignments.
