Hi, I have progress bar              

_progressView = new IGProgressView (IGProgressViewStyle.IGProgressViewStyleRadial);
            _progressView.Progress = 0.30f;
            _progressView.RadialInsertScale = 0.7f;
            _progressView.ProgressTintColor = UIColor.Orange;
            _progressView.ProgressTrackTintColor = _grayColor;
            _progressView.RadialContentView = new UILabel {
                Text = "30%",
                TextAlignment = UITextAlignment.Center,
                TextColor = UIColor.Orange,
                BackgroundColor = UIColor.Clear
            };
            _progressView.RadialInsertTintColor = View.BackgroundColor;

            _progressView.Frame = new RectangleF (10f, 270f, 100f, 100f);
            _scrollView.Add (_progressView);

When i set progress property, value is changed with out animation. How can I enable animation.
