Based on Камен Великов's answer:

You can mark your bindings as to be updated manually by defining

yourTextBox.GetBindingExpression(TextBox.TextProperty).UpdateSource();
when Save is clicked.

Please note, if there are updated to the binding source triggered from anything else, they are still shown directly in the UI.
