Bound Textbox/Labels not updating when OnPropertyChanged fired

Question

I have a simple application which uses a BindingList<(Person)>, people, to store information about employees (Windows Forms). Person has several properties such as Name, DateOfBirth, etc and implements INotifyPropertyChanged.

The BindingList<(Person)>, people, is bound to a binding source. A DataGridView control is bound to this source, and as expected property changes are updated on the DataGridView. For example, when I change the age of a person the DataGridView updates immediately.

My problem occurs when I use the same binding source other controls. I have the text property of a text box bound to Person.Name, using the same binding source as the DataGridView. Changes to the Person.Name property update on the DataGridView, but not to the text box.

How can I make the text box update, like the DataGridView, when a property changes?
