How to refresh a simple binding of a windows forms control?

Question

I'm binding a domain objects property to the Text property of a System.Windows.Forms.Label using the DataBindings.

Label l = new Label();
l.DataBindings.Add(new Binding("Text",myDomainObject,"MyProperty"));

However, when I change the domain object, the Label does not reflect the change. I know that for complex Controls like the DataGridView, binding can be done with a BindingSource on which I can call ResetBindings, but I couldn't find any method to update the binding in the simple case of a Label.

Answer 1

Your domain object should implement INotifyPropertyChanged so that the binding knows when the underlying property has changed.
