I would like to add a slider to cammand controls in a RibbonPage. I know there is a CExtBarSliderButton, which can be placed on the CExtToolControlBar. Since RibbonPage inherets from CExtToolControlBar, is there a way to use the same mechanism?

Thanks.

You can put CExtBarSliderButton and any other CExtBarButton-derived objects into a ribbon as well as into a toolbar. But in the case of a slider or a scroll bar button, you should use an adopted version of the CExtBarSliderButton class (see the CRibbonSliderOrScrollBarButton class in the source code below) and you should create and use a ribbon node class which inserts an adopted button class into the ribbon (see the CExtRibbonNodeSliderOrScrollBar class in the source code below):
