How do I detect NSDatePicker ValueChanged in MonoMac?

Unlike UIDatePicker in Monotouch, the NSDatePicker in MonoMac does not appear to have "ValueChanged". How do I detect changes?

Ideally where datePicker is an NSDatePicker, I want to 

datePicker.ValueChanged += DatePickerOnValueChanged

For events, I see "Activated" and "ValidateProposedValue", could it be the latter that I want?

Update. I think I can do something like below. Is it equivalent?

datePicker.Action = new MonoMac.ObjCRuntime.Selector ("datePickerAction:");

and

[Export("datePickerAction:")]
private void datePickerAction()
{
    // stuff
}

In your ideal case, you say you want to use an event. The ValidateProposedValue event is fine for this:

picker.ValidateProposedDateValue += (object sender, NSDatePickerValidatorEventArgs e) => {
            Console.WriteLine(e.ProposedDateValue);
        };

It seems to correspond to the NSDatePickerCellDelegate method datePickerCell:validateProposedDateValue:timeInterval:, which is what I would use in Objective C.
