Hello,

See our RibbonSample Samples\Ribbon\RibbonSample\MainFrm.cpp

BEGIN_MESSAGE_MAP(CMainFrame, CXTPFrameWnd)    ....
    ON_NOTIFY(TCN_SELCHANGE, XTP_ID_RIBBONCONTROLTAB, OnRibbonTabChanged)
    ON_NOTIFY(TCN_SELCHANGING, XTP_ID_RIBBONCONTROLTAB, OnRibbonTabChanging)
    ....
END_MESSAGE_MAP()

void CMainFrame::OnRibbonTabChanged(NMHDR* pNMHDR, LRESULT* pRes) 
{
    NMXTPTABCHANGE* pNMTabChanged = (NMXTPTABCHANGE*)pNMHDR;

    if (pNMTabChanged->pTab)
    {
        TRACE(_T("Tab Changed, Caption = %s\n"), (LPCTSTR)pNMTabChanged->pTab->GetCaption());
    }
    
    *pRes = 0;
}

void CMainFrame::OnRibbonTabChanging(NMHDR* /*pNMHDR*/, LRESULT* pRes) 
{

    *pRes = 0;    
}

Code which handle these messages is

BOOL CXTPRibbonBar::OnTabChanging(CXTPRibbonTab* pTab){
    NMXTPTABCHANGE nm;
    nm.pTab = pTab;

    return (BOOL)m_pControlTab->NotifySite(TCN_SELCHANGING, &nm);
}

void CXTPRibbonBar::OnTabChanged(CXTPRibbonTab* pTab)
{
    NMXTPTABCHANGE nm;
    nm.pTab = pTab;

    m_pControlTab->NotifySite(TCN_SELCHANGE, &nm);
}

[File] is not ribbon's tab, it is "systemButton" which call BackStage.

I can't find how catch that event, but can offer to handle message of changing backstage tab, which also raised when backstage became visible.

BEGIN_MESSAGE_MAP(CMainFrame, CXTPFrameWnd)
    ...    ON_MESSAGE(WM_XTP_COMMAND, OnBackstageTabChanged)
END_MESSAGE_MAP()

LRESULT CMainFrame::OnBackstageTabChanged(WPARAM wParam, LPARAM lParam)
{
    UNUSED_ALWAYS(wParam);

    NMXTPCONTROL* tagNMCONTROL = (NMXTPCONTROL*)lParam;
    if (tagNMCONTROL && tagNMCONTROL->hdr.code == XTP_BS_TABCHANGED)
    {
        CXTPRibbonBackstageTab* pNewTab = DYNAMIC_DOWNCAST(CXTPRibbonBackstageTab, tagNMCONTROL->pControl);
    }

    return 0;
}

I have tested and unfortunately found that CMainFrame::OnBackstageTabChanged() isn't raised when backstage have only commands, without tabs.

Take this into account.
