I override CreateWindowHandle (in a child TIB_ComboBox):

procedure TIB_ComboBoxEx.CreateWindowHandle(const Params: TCreateParams);
begin
inherited;
if not FFlag then
try
FFlag := true;
if ThemeServices.ThemesEnabled and IsWinVista and (Parent is
TIB_CustomGrid) then
SetWindowTheme(Handle, ' ', ' ');
finally
FFlag := false;
end;
end;



IsWinVista is a function of Jcl.

Hope it helps.
