Can you provide more info on what you want to do and what problem you're having? If you want to display a calendar directly within a RibbonGroup then you can add it to the RibbonGroup's Items collection but since the height of the ribbon group is fixed as per fhe Office UI Guidelines the calendar could get clipped although you could put it into a ViewBox to have it scaled down. If you want a dropdown calendar then you can put a xamMaskedEditor into a RibbonGroup's Items collection.
hey andrew,
i just want to add a calendar control in the ribbon group which will be shown if button in the ribbon is clicked.
i think i will try your solution mentioned above.
