I need load old data by scroll up about react-virtualized HOT 7 CLOSED

This is a little tricky. You could try using a combination of onRowsRendered (to monitor which row the user has recently scrolled to) and scrollToIndex (to ensure that that row is still visible after you've unshifted. But in general I don't try to support this because a change in rowsCount could mean entirely new data.

I'll leave this issue open for discussion for now. Let me know if that approach has any promising results.

This will bad on UX, it's not smooth
I recommend we need to have a config to display As A Chat or Message Box (displayBottomUpwards mode) to get the old msg.

Fair enough. But realistically I don't think I'll have the bandwidth to get to this any time too soon.

I'll leave the ticket open, tagged as "help wanted", in case anyone else feels more inclined to implement this though. :)

Hi how about we have a config to prepend on the DOM like jQuery prepend a div?

Check this demo:

I don't see how that would work with a library like react-virtualized. Allowing external code to modify the DOM in any way would make the virtualization too fragile.

Closing for now due to lack of a response and/or a clear path forward.
