Datagridview row font not resized when form is resized

[malaygal]

I have set all cells (column headers, row cells) of the Datagridview to 8.25 tahoma. When the form is resized, all the column header fonts are resized, but the rowcells remains at 8.25. I checked and set all the dgv font properties that I can think of (defaultcellstyle , rowdefaultcellstyls, row template ( enable resizing), but nothing seem to work.
Any help would be greatly appreciated.
