Modify CDlgGridDlg::OnInitDialog()

This step modifies OnInitDialog to subclass the user control on the dialog template and to perform some basic grid initialization.

1. Open DlgGridDlg.cpp.

2. Add the following line after #include "stdafx.h":

#include "MyGridWnd.h"

3. Search for OnInitDialog.

4. Replace the // TODO: line with the following code:

// Please refer to the MFC documentation on

// SubclassDlgItem for information on this

// call. This makes sure that our C++ grid

// window class subclasses the window that

// is created with the User Control.

m_wndGrid.SubclassDlgItem(IDC_GRID, this);

// Initialize the grid. For CWnd based grids

// this call is essential. For view based

// grids this initialization is done in

// OnInitialUpdate.

m_wndGrid.Initialize();

// Sample setup for the grid

m_wndGrid.GetParam()->EnableUndo(FALSE);

m_wndGrid.SetRowCount(100);

m_wndGrid.SetColCount(20);

m_wndGrid.SetStyleRange(CGXRange(1,1),

CGXStyle()

.SetValue("Hello")

);

m_wndGrid.SetStyleRange(CGXRange(1,2),

CGXStyle()

.SetValue("World!")

);

m_wndGrid.GetParam()->EnableUndo(TRUE);

5. Save and close DlgGridDlg.cpp.
