Today we’ll talk about a little bit advanced topic like Data Binding. It’s really useful when you’ve massively structured code, and you’ve handle a lots of data, not like our typical contols, e.x., textBox1.Text = “Hello, world!”; Data Binding is nothing but creating a ViewModel class, which actually contains the data. One more important thing, you must follow in Data Binding control is INotifyPropertyChanged. It actually gives you an alert, when a property value is changed. Just like hey there, I’m changed. We’ll come back it later.
