Hi Kenneth Jackson,
Thank you for writing me.
Yes, you are correct - part of the functionality is implemented in the base classes, but the other part required is implemented only in RadRibbonBar
at the moment. This enables us to provide screen tips for all our controls/elements at a relatively small development cost.
We do not have a specific timeframe when it will be implemented for the rest of the controls, and we'll keep you posted as this functionality becomes available.
If you have any additional questions, please contact me.
All the best,
the Telerik team
