Modify DlgGrid's stdafx.h
Gxall.h is the core Objective Grid header file. Once this file is added all required classes will be available to you inside your application. This is similar to including afx*.h.
1. Open stdafx.h.
2. Add the following line at the end of the file:
#include "grid\gxall.h"
3. Save and close stdafx.h.
