CMFCPropertyGridCtrl issues in a CDialog

[EDN Admin]

Hello Fellows,<br/> <br/> Im trying to use a CMFCPropertyGridCtrl into a dialog application. I replaced the CDialog base class with CDialogEx and then took some source given as example with any MDI new generate project applications. Here are the interesting bits under<br/> <br/>
<pre>// CPropertiesDialogDlg.h
class CPropertiesDialogDlg : public CDialogEx
{
...

CFont m_fntPropList;
CMFCPropertyGridCtrl m_wndPropList;
protected:
virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
public:
void InitPropertyGrid(void);
void SetPropListFont(void);

...
}

// CPropertiesDialogDlg.cpp
...
void CPropertiesDialogDlg:oDataExchange(CDataExchange* pDX)
{
CDialog:oDataExchange(pDX);
DDX_Control(pDX, IDC_LIST1, m_wndPropList);
}


BOOL CPropertiesDialogDlg::OnInitDialog()
{
...
InitPropertyGrid();
...
}


BOOL CPropertiesDialogDlg:reCreateWindow(CREATESTRUCT& cs)
{
CRect rectDummy;
rectDummy.SetRectEmpty();

if (!m_wndPropList.Create(WS_VISIBLE | WS_CHILD, rectDummy, this, 2))
{
TRACE0("Failed to create Properties Grid n");
return -1; // fail to create
}

return CDialog:reCreateWindow(cs);
}


void CPropertiesDialogDlg::InitPropertyGrid(void)
{
SetPropListFont();

<br/> Has anybody been successful with this?<br/> <br/> The list of undesired symptoms are:<br/> - Assertion errors switching from one Property object to another (~every second object you click into)<br/> - Missing icons on the spin buttons<br/> - Property column invisible, you must click on the left side of the grid ctrl to be able to re-size it.<br/> <br/> Thanks in advance!<br/> <br/> -Damien
