How to check the ESC key in a StringGrid?

Hi;

there's a way to check if a user press the ESC in a StringGrid?; i tried
with OnKeyDown and OnKeypress but i can't check the ESC key, the prog just
leave the StringGrid a pass the control to the next edit.

TIA

Does not work that way!, the focus leaves the component before the onKeydown
evaluation takes place...

try this
procedure TForm1.StringGrid1KeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);;
  col,row:integer;
begin
if key=VK_ESCAPE THEN
begin
col:= Tstringgrid(sender).col;
row:=Tstringgrid(sender).row;
Tstringgrid(sender).cells[col,row]:='press esc key in
cell['+inttostr(col)+','+inttostr(row)+']';

end;
end;

Just to clarify:

My problem was due a corrupted keyboard driver, after i reinstall windows,
the problem disappear.
