Subject: Re: [DUG] PageDown in StringGrid
Thanks, Corey
I've handled that problem now.
The current problem (for anyone reading) is:
If your app is exhibiting a certain behaviour, and there are no obvious
events driving
this behaviour, is there a way of finding out which code in the app IS
causing the
said behaviour.
eg I have a StringGrid with NO KeyDown event coded for that particular
grid, yet
when I press say, PageDown when the grid has focus, then the cursor is moved
to
the last line of the grid. But I'm blowed if I can find the code that is
doing that. I
can't find any reference that the behaviour is built in to TStringGrid.
In exasperation
