Same problem here.. Im writting WTL aplication and suddenly for one of my view events list in properties window is gone. By pure luck, I have found solution. In my code view class was inherited from multiple base classes. I have commented one of the classes and event list was empty:
class CXXXView :
public CDialogImpl<CXXXView>,
public CDialogResize<CXXXView>,
public CWinDataExchange<CXXXView>,
COffscreenDraw<CXXXView>,
//public CCtlColored<CXXXView>,
CDropFilesHandler,
ITimeLineListener
I just removed commented line, save h file and events is back. Make sure you have
enum { IDD = IDD_XXX_FORM };
in your h file.
