I am looking for information on how to put a calendar/datepicker control into a WPF Ribbon. Has anyone done this before? What is the best way to implement this?
There is no DatePicker or Calendar control available with Ribbon controlset.
But you can add the WPF dataPicker control to it, but it will look odd there. I dont know why you need to add a Calendar or DatePicker control there. Ribbons are generally suited for commands.
