You can handle the scrollerScrolled delegate of the EnhancedScroller. Just add the handler right after you set the scroller's delegate to the controller. Something like:

           scroller.Delegate = this;
           scroller.scrollerScrolled = ScrollerScrolled;

Then in the handler, you can check the position of the scroller. If it is at the bottom (or right in the case of a horizontal scroller) then you can add data and reload. Something like:

       private void ScrollerScrolled(EnhancedScroller scroller, Vector2 val, float scrollPosition)
       {
           if (scroller.NormalizedScrollPosition == 1f)
           {
               _data.Add(new Data() { someText = "New Row" });
               scroller.ReloadData(1f);
           }
       }

I'm not sure what you mean. Be sure you call ReloadData after adding new data in the controller. That will refresh the scroller and show the newly added items.

Vector2 anchorPos = scroller.ScrollRect.content.anchoredPosition;

scroller.ReloadData();

scroller.ScrollRect.content.anchoredPosition = anchorPos;

use this code to reload data at the same position
