Hi,

Thanks

Support’s answer to a similar question:
The MFC’s command updating mechanism is used in the ribbon bar absolutely like in toolbars and menus. So simply add the command updating handler for a button and invoke pCmdUI->Enable( FALSE ) to disable it either in the ribbon bar or menu. Please note that in the RibbonBar sample, all the commands are forcibly made enabled by returning TRUE value in the CMainFrame::OnCmdMsg() virtual method and not invoking parent class methods. If you are using the RibbonBar sample as a start up project, you should fix this issue. The CMainFrame::OnCmdMsg() virtual method typically invokes the main SDI view’s OnCmdMsg() method and the parent class method.
