scrollView = new UIScrollView(
         new CGRect(0, 80,View.Frame.Width
                    , View.Frame.Height -200));
        View.AddSubview(scrollView);

        scroll2.ScrollEnabled = true;
        scroll2.ContentSize = new CGSize(0f, 1760f);
        scrollView.ScrollEnabled = false;

ImageService.Instance.LoadUrl(GlobalVar.imgpath + travelerlistdetail.orderDetails.product_image) .Retry(3, 200) .DownSample(100, 100) .Into(ImgProd);

            //scrollView.ContentSize = ImgProd.Size;
            scrollView.AddSubview(ImgProd);
            scrollView.MinimumZoomScale = 0.9f;
            scrollView.MaximumZoomScale = 3f;
            //scrollView.PinchGestureRecognizer.Enabled = false;
            //await Task.Delay(2000);
            //scrollView.ContentSize = ImgProd.Image.Size;


            scrollView.ViewForZoomingInScrollView += (UIScrollView sv) => { return ImgProd; };

            UITapGestureRecognizer doubletap = new UITapGestureRecognizer(OnDoubleTap)
            {
                NumberOfTapsRequired = 1 // double tap
            };
            scrollView.AddGestureRecognizer(doubletap);

private void OnDoubleTap(UIGestureRecognizer gesture) { scroll2.ScrollEnabled = false; scrollView.ScrollEnabled = true; if (scrollView.ZoomScale > 1) scrollView.SetZoomScale(0.25f, true); else scrollView.SetZoomScale(3f, true); }

scroll2 is total page's scroll and scrollview is the imageview scroll when zoom in
