Hi guys,

We have two containers, Header and main section, the Main Section is scrollable.

When the user scrolls, is there a way to know that scrolling is happening? (OnScroll?)

We would like for example change the size of the Header, if the user scrolled down, and go to normal, if the user is at the top most scrollable item...

Thanks in advance.

Hi @pre , Thanks for this, useful, but not what I am looking for...
Is there a way to know the scroll position? Say you have the canvas with 20 items, when scrolling down, and reaching the bottom, I want to say "You have reached the bottom" When Scrolling up, and reach the top, I wan to say " Reached the Top" etc.. as you scroll, some items are going to be scrolling off the screen, and some are coming into display, would be great to know which is displayed and which is not displayed in the canvas small window.
Thanks in advance. Fadi

So far we found nothing, so we had to re-implement the scrolling with our version to be able to know this.. For a low code, we seem to have to write a LOT of code.

I figured this out. I have a Vertical Container. Below it, I have an arrow pointing down to let the user know that there is more content in it. The last item in my container is called lastItem (for example). The arrow's visibility is set to lastItem.Y>=-200 (-200 being the distance one has to scroll to get to the bottom). This is also how you can check how far a user has scrolled.
