No notification message from custom button

 

I met a strange problem with XTP 11.2.1. I inserted a propertygrid on a pane, and I also created a CXTListCtrl on that pane. I could catch the notification message through OnGridNotify() when I clicked the standard grid items. Then I inserted some custom button as grid item into the propertygrid(same as GridSample) , but I couldn't catch the notification message through OnGridNotify() when I clicked custom button.

 

What's the problem...?

 

some of my code:

 

BEGIN_MESSAGE_MAP(CPropertiesPane, CWnd)
     ......

     ON_MESSAGE(XTPWM_PROPERTYGRID_NOTIFY, OnGirdNotify)

END_MESSAGE_MAP()

 

LRESULT CPropertiesPane::OnGirdNotify(WPARAM wParam, LPARAM lParam)
{
     int nGridAction = (int)wParam;

     .....

}

 

int CPropertiesPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CWnd::OnCreate(lpCreateStruct) == -1)
       return -1;

  

    ......

    if (m_wndPropertyGridPart.GetSafeHwnd() == 0)
    {
        m_wndPropertyGridPart.Create(CRect(0, 0, 0, 0), this, 0xf0);
        m_wndPropertyGridPart.SetOwner(this);
        m_wndPropertyGridPart.SetTheme(xtpGridThemeDefault);
        m_wndPropertyGridPart.ShowHelp(FALSE);

    .....
}
