Question

I have created a Generic WPF Control, so the layout is all defined in code. This is all fine and I have added bindings which work first time round, for example:

private bool btEnabled { get { return SOME_LOGIC; } }

Button bt = new Button { Content = "Button" };
bt.SetBinding(Button.IsEnabledProperty, new Binding { Source = btEnabled, Mode = BindingMode.OneWay });

Whenever something happens which affects btEnabled property I am calling INotifyPropertyChanged but the PropertyChanged event is always null, I can’t work out why the binding isn’t registering the PropertyChanged event.

Any Ideas?

Thanks

I see that btEnabled is a property, that too private!

So presumably there are two mistakes…

Your Binding should set Path="btEnabled" not Source=btEnabled
And your btEnabled property should be public.
