FontFamilyComboBox: Preview vs. UndoStack

Ribbon for WPF Forum

Hello everybody,

we have noticed (in your SampleBrowser, too) that previewing a FontFamily from the FontFamilyComboBox (--> 'ValueCommandParameterAction.Preview') already adds to the UndoStack of a RichTextBox. Our expectations were, indeed, that this only happens in the 'ValueCommandParameterAction.Commit' case.

So, can you tell me how to achieve this?

Thanks in advance,

Hi Detlef,

Unfortunately we haven't found a way around that with the RichTextBox API, to prevent it from happening.
