Scroll bars on the WPFapplication are not identified by Object spy

I am a newbee to TestComplete but trying to implement a framework for one of our Project.

It's a WPF application(using dev-ex controls).

I found an issue in idetifying the object.

Object spy is not recognising the scroll bars and so we are unable to perform any action on it.

Can anyone guide me on the same? Is there any possible way other than objectspy in order to work on the scroll bars?
