Create CXTPropertyGrid error!

I need a CXTPPropertyGrid Control in a formview and hope to dock the formview
So I create a CXTPPropertyGrid object in CSimpleFormView which is docked as a pane.But the codes doesn't work!

The codes are as follows:

void CSimpleFormView::OnInitialUpdate()
{
    CFormView::OnInitialUpdate();
    
    // TODO: Add your specialized code here and/or call the base class
    CRect rc;
    m_wndPlaceHolder.GetWindowRect( &rc );
    ScreenToClient( &rc );
    if (m_wndPropertyGrid.Create( rc, this, IDC_PROPERTY_GRID ) )
    {
       
        CXTPPropertyGridItem* pSettings    &nbs p;   = m_wndPropertyGrid.AddCategory(_T("Stand Settings"));

        CXTPPropertyGridItem* pItem = pSettings->AddChildItem(new CXTPPropertyGridItemBool(_T("Video"), TRUE));
        pSettings->AddChildItem(new CXTPPropertyGridItemBool(_T("Door"), TRUE));
        pSettings->AddChildItem(new CXTPPropertyGridItemNumber(_T("Count")));

        pSettings->Expand();
        pItem->Select();   
    }
}

I use Xtreme Toolkit Pro v9.601 Windows2000.
