Actually, size of dropdown button use system metrics for size.
If you want to change this and use a specific size, you can change
CGridCellCombo::Draw method in MFCGrid\GridCellCombobox.cpp.
This method draw a combobox cell.
I think you can only change this line:
For rebuild Win32::GUI::Grid, you need to download Sourcecode.
(from here : http://perso.club-internet.fr/rocherl/Win32GUI.html#Grid)
Unzip it in a directory, made change in Draw method and build it.
for build Win32::GUI::Grid
perl makefile.pl Create Makefile
nmake Build Win32::GUI::Grid
nmake install Install Win32::GUI::Grid
for only build MFCGrid lib, run nmake in MFCGrid directory.
You need Visual 6 C++ (and MFC lib).
