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.
