It looks like these XYToCell, YToRow, and XToCol methods don't work quite
the way I need. My grid actually has scroll bars that go to the right and
left as well as up and down (I didn't think to mention this earlier;
sorry!). All of these methods only calculate on what is currently shown
onscreen, which breaks their functionality for my purposes anyway. For
example, if I need the cell value in (0,0) and I've scrolled 3 columns to
the right, then I end up with (0,3)'s value instead.

Also, when I tried to set the tooltip string for the cell I was mousing
over by doing the following:

event.GetEventObject().SetToolTipString('My message')

it didn't always update when I'd move to another cell and instead,
retained the previous value of the tooltip. Does anyone know how to fix
either of these issues?
