Interface IInvalidValueStrategy

public interface IInvalidValueStrategy

This interface is used to determine how to handle invalid values entered by the user. An implementation of this interface will be called on leaving a field or when the Ok button (with defaultaction set to save) is clicked. You can only set one strategy per part. Both methods are always called, so if you don't want to use a checking on a form level, just return true form that method.
