Hi

I am going to build a scroll view component without using JS interop.
The view and scroll bar is separated so I want to know the scroll position in the scroll bar.
How can I know the scroll position in onscroll event?

@SteveSandersonMS, I assume there is currently no parameter passed to the scroll event handler, which represents this information?

It will be great if scroll event will provide all necessary data.

Before that you can check this blazor scrollbar component prototype, svg based, no js.
