Property Grid as Dockable Pane?

What is the right way to create a property grid as a dockable pane?  I tried modifying the MFC ToolkitPro template such that the declaration of the pane was:

CXTPOfficeBorder<CXTPPropertyGrid> m_wndProperties;

The window did indeed show up as a property grid (I could see the help section below), but no matter what I do in the OnCreate routine, I can't get any items added to the grid.  Here's what I'm trying to do:

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) {
    // ...
    CXTPPropertyGridItem* pCategory = m_wndProperties.AddCategory(_T("Example Category"));
    CXTPPropertyGridItem* pItem = pCategory->AddChildItem(new CXTPPropertyGridItemNumber("Example Number"));
  // ...
}


This code compiles and runs just fine, but the property grid stays blank instead of showing the added item.

Any hints?

The GUI_Whidbey led me to the correct answer.  After a grid.Create(...) call, you have to do grid.SetOwner(...), otherwise the grid will never paint.

Thanks.
