[SOLVED] Open Backstage Page Programmably

void CMainFrame::OnViewShowHide(UINT nID)
{
    //m_bOptions[nID - ID_VIEW_RULER] ^= 1;
    
    pRibbonBar->SetPopuped(0);	//popup Backstage

    CXTPRibbonBackstageView *pView = DYNAMIC_DOWNCAST(CXTPRibbonBackstageView, pRibbonBar->GetSystemButton()->GetCommandBar());
    if (pView)
    {
        CXTPControls* pRibbonControls = pView->GetControls();

        int nCount = pRibbonControls->GetCount();
        for (int i=0; i < nCount; i++)
        {
            CXTPRibbonBackstageTab* pTab = DYNAMIC_DOWNCAST(CXTPRibbonBackstageTab, pRibbonControls->GetAt(i));
            if (!pTab)
                continue;

            if (pTab->GetID() == ID_BACKSTAGE_PRINT)
                pView->SetActiveTab(pTab);        //to exclude searching we can save pTabPrint pointer on creation.
        }
    }
