Thank you for writing.
property is not supported for the elements, but only for controls, since you can tab only from a control to a control, not from an element to another element in one and the same control.
Since this forum thread is in the RadRibbonBar section, I suppose that you want to tab through the elements in the RadRibbonBar control. As I mentioned, you cannot tab through the elements, but for RadRibbonBar you should use key tips
and short cuts instead. This comes from the design specifications of Microsoft.
Do not hesitate to contact me again, if you have other questions.
