Since You are using MVVM so you can add a small business logic in your model property :

Like this :

        private string _translation;
        private bool _isTranslated;

        public string Translation
        {
            get { return _translation; }
            set
            {
                _translation = value;
                IsTranslated = !String.IsNullOrEmpty(_translation);
            }
        }

        public bool IsTranslated
        {
            get { return _isTranslated; }
            set
            {
                _isTranslated = value;
                OnPropertyChanged("IsTranslated");
            }
        }
