As we know, this is not possible in our actual grid control.
Then reading at little bit more at: Multi-line (merged) datagridview header I saw this that it could interesting to be read:

Difference between datagridview and listview control

Whos knows this could let us to reach another proper results ? It could ?

DataGridView is from Windows Forms (.Net) and not Win32 API.

I think it requires fundamental changes to HMG library.

Yes, I think so...

Thank you Rathi for your reply

Nice idea Pablo, now I use labels to simulate this effect.
It works actually very fine, labelfont, color etc. is, of course, no problem.
You only have to keep them together..

Serge,

Can you show me how?

There is something of curious in this demo (based on ..\SAMPLES\Controls\Grid\GRID_18).

I just over-wrote the 02.bmp file with larger size it simulates two lines.

When run the builded demo, enlarged image can diffusely be displayed. But when we go to first menu option (Change Column 1 Header Image) displays litle better but in column 1 and two.

The big question (most probably Claudio can gives his opinion & tip): Height of grid header, did not changed...

If we could control the height of the header by the size of the image, it would be more interesting to use HEADERIMAGES.

Rathi, This is very simple and basic:

just put a LABEL at (for example) 10,10 and your GRID at 30,10 then. It's a bit dirty.
Then do the same for each column in the grid!

My minigrid sample can be used for small number of rows. It uses labels so every cell can have different font, color etc.
One of limitations is that user can't change width of column.

Hi Marek, of course you can. By LISTVIEW_SETCOLUMNWIDTH C function.

And at HMGDoc:

- New Set Properties:
 
            <ParentWindowName>.<GridControlName>.ColumnHEADER           ( nColIndex )  := cColumnHeader
            <ParentWindowName>.<GridControlName>.ColumnWIDTH            ( nColIndex )  := [ nColumnWidth ] |

I was writing about my minigrid based on labels
