Introduction
It is a very simple grid. It is a custom control derived from CWnd. It is inspired by 
the excellent Delphi TGridView component written by Roman Mochalov. Header 
of the grid is a separate logical object (separate from non-#xed, "working" part of 
the grid). Non-#xed part of the grid can work only in virtual mode, i.e., data for 
display is stored outside the grid and loaded only by query when the grid needs 
repainting. That is why the grid is called "virtual". If you don't understand my 
explanation of control's "virtuality", then I'd recommend you to read "Virtual list 
view description" of CListCtrl in the MSDN help.
The control features:

 derived from CWnd, though has almost all CListCtrl features (in virtual

mode);

 can be tuned to look like CListCtrl in report mode;

 smooth horizontal cell scrolling;

 title tips for both header sections and regular cells;

 possibility to forbid setting the cursor for certain cells;

 multiline, multisectional, hierarchical (with possibility of designing one

section per several columns) grid header as separated (from regular cells)

logical object;

 code auto-generation for columns and header construction;

 possibility of word wrap in grid header;

 header sections can be 2at or 3D (button-like);

 handling of mouse-clicking at header cells (in button mode);

 in-cell edit and combo controls (appropriate style can be set for each cell

individually);

 changing column width with mouse at runtime (with possibility to forbid

this operation for certain columns);

 column width constraints (min width / max width restrictions);

 cell text alignment for each cell individually (left, right, center);

 in-cell images;

 in-cell check controls (check box-like or radio button-like);

 #xed columns (always in the left side of the grid);

 #xed columns can be 2at or 3D (button-like);

 single cell selection (default) or whole row selection;

 background and text colors for each cell individually;

How to use

First, insert into your dialog template custom control. Just like this:

Don't forget to write "CVirtualGridCtrl" as the class name in the Custom

Control Properties dialog box.

Second, include VirtualGridCtrl.h in your dialog's header #le and declare a variable

of type CVirtualGridCtrl. It goes something like this:

Collapse Copy Code

//{{AFX_DATA(CVirtualGridDemoDlg)

//}}AFX_DATA

CVirtualGridCtrl m_grid;

Third, add next line in the DoDataExchange function of your dialog CPP source

#le. Like this:

Collapse Copy Code

//}}AFX_DATA_MAP

DDX_Control(pDX, IDC_GRID, m_grid);

Note

Alternatively, you can use CVirtualGridCtrl::Create:

Collapse Copy Code

CVirtualGridCtrl m_grid;

bSuccess = m_grid.Create(rect, pParentWnd, nID);

where rect is the dimensions, pParentWnd is the parent window, and nID is the

ID. This could be the only way to use custom controls in some cases (e.g., if you're

writing something based on speci#c MFC extensions, such as AutoCAD's

ObectARX application).

Fourth, add the following #les to your project:

 VirtualGridCtrl.h and VirtualGridCtrl.cpp

 GridButton.h and GridButton.cpp

 GridEdit.h and GridEdit.cpp

 GridListBox.h and GridListBox.cpp

 TitleTip.h and TitleTip.cpp

 MemDC.h

If you run the project after completing all these operations, you'll see such a

thoughtful picture:

Actually, I'm not sure this result would suit you. So what to do next? You're

probably thinking I'll give you some boring instructions such as "add some code",

"add this line", "add that line", "press Enter" etc.? I'm glad to disappoint you. Let's

walk another way. Launch demo executable. In the demo application window,

press the "Header and columns properties" button. You'll see something like this:

In the "Columns" list view, shift-select all items and delete them by clicking the

"Remove" button: we're going to start from scratch. Click the "Apply" button, and

then click the "Add" button six times. This will add six columns to the grid with

default parameters (column's caption is empty, width is 64, max width is 10000

etc.). Press the OK button. Our dialog box would look like this:

Drag manually (I mean using mouse) header sections to be like this:

Click the "Header and columns properties" button again and go to "Headers"
