Why OnInitDialog not called?

I have a CXTPDockingPane in my ChildFrame.  The docking pane is attached to a CXTResizeDialog.  I wanted to do a few initializations in the OnInitDialog and controls resizing, but the function CXTResizeDialog::OnInitDialog was not called at all.  What did I do wrong?

I am using v9.601 pro.  Thanks in advance for any helps!

///////////////////////// Code ///////////////////////////

m_pwndContractSelector = m_paneManager.CreatePane ( IDR_PANE_CONTRACT_SELECTER,

                  m_paneManager.GetC lientPane() );

    m_dlgContractSelector = new CXTResizeDialog();
    m_dlgContractSelector->Create(IDD _CONTRACT_SELECTOR,this);

    m_pwndContractSelector->Attach( m_dlgContractSelector );

    m_pwndContractSelector->SetOption s(xtpPaneNoCloseable);

 //   m_pwndContractSelector->GetChil d()->SendMessage(WM_INITDIALOG);

Hi Warren:

Thanks for your help.

I tried every poosible way of putting a dialog (CDialog or CXRResizeDialog) into a docking pane and got stuck at the very same point - OnInitDialog() call.  Not sure why this happens and I don't want to get into creating the controls using code in stead of using resource editor.

In the mean time, I just went back to a regular popup dialog to but I will always be interested in knowing if some one has the same issue and figured out the answer.

Thanks.
