I have tested the provided column and it is not the reason why scrolling is not working. Perhaps you have a custom cell as well and if so, you should make sure that you properly set the ShouldHandleMouseInput and NotifyParentOnMouseInput properties of the elements in the custom cell to allow notification of the grid.
If you still have issues, you can make a small sample using your column and demonstrating how the scrolling does not work, so I can investigate the precise case and help you resolve it.
I am looking forward to your reply.
