How to create a subclass for special control (like stingray 
grid class) so that you can create an override


1. Create class derived from grid class to catch events


xxgridctrl.cpp




xxgridctrl.h


class xxGridCtrl : public CGXGridWnd //derived from grid class
{
// Construction
	public:
		xxGridCtrl();


2. Add these lines to the containing dialog file


xxdialog.cpp:


void xx::DoDataExchange(CDataExchange* pDX)
{
	CPropertyPage::DoDataExchange(pDX);
	//{{AFX_DATA_MAP(CxxPropertyPage)
	// NOTE: the ClassWizard will add DDX and DDV calls here
	DDX_Control(pDX, IDC_GRIDXX, m_GridXX); // Create DDX for grid control
	//}}AFX_DATA_MAP
}


xxdialog.h:


class xxPropertyPage : public CPropertyPage
{
	DECLARE_DYNCREATE(xxPropertyPage)


// Construction
public:
	xxPropertyPage();
	~xxPropertyPage();


// Dialog Data
	//{{AFX_DATA(xxPropertyPage)
	enum { IDD = IDD_xxxxxx };
	xxGridCtrl m_Gridxx;  // create data member for grid control
		// NOTE - ClassWizard will add data members here.
		//    DO NOT EDIT what you see in these blocks of generated code !
	//}}AFX_DATA


3. On grid control, set the class to GXWND
