[Gambas-user] What exactly does the Clear method in a GridView?

[Bruce]

Well I was wrong!  Had a good look though our local code and found that 
our gridview override class does an explicit "Me.Rows.Count = 0" in it's
Clear() method.  :-(

(That code (ours) has been around so long, I don't even remember when I, 
or someone, implemented the explicit setting of the rows count to zero.)
Which begs the question...

Oh well, sorry about the noise.
