This question was recently answered in a private support case, and I thought I'd share it here in the forums:
Q: Should setting IsDirectionReversed swap the increase and decrease buttons on the XamSlider?
A: IncreaseButton and DecreaseButton don't change their positions when IsDirectionReversed is turned on. The developer is responsible to change its positions in the control template or to change the attached commands.
Hello,
I have learned from our engineers that this issue was addressed in our latest Service Release, which was made available on August 8, so I would recommend trying the new release and let me know if this resolves the issue.
Thanks,
We have an XamNumericSlider in our application that has Orientation=Vertical and IsDirectionReversed=True. When we click on the top arrow, the value increasese, but we would like to see it decrease and clicking on the bottom would increase the value.
I saw your post here about this issue. Is there an example somewhere that shows how to change the positions of the IncreaseButton and DecreaseButton or how to change their attached commands?
