Thanks for your reply...

This is the path I have basically taken; here are the specifics:

1. To determine the number of rows, I use a similar algorithm to the one above, but I take into account the scroll bar.

if grid.RowHeight = 0
    lnRowCount = 1  && Just in case
else
    lnRowCount = (grid.Height - grid.HeaderHeight - ;
        iif(inlist(grid.Scrollbars, 1, 3), sysmetric(8), 0) - 1) / ;
        grid.RowHeight
    lnRowCount = int(max(1, lnRowCount))
endif

2. To find the number of visible rows, I just opened the bound alias and again in another work area (so as not to disturb the original) and skipped forward to a maximum of lnRowCount to find out how many rows I can really move.

3. I encountered one other problem: The newly selected grid cell did not have its text selected like it was supposed to (when the SelectOnEntry property is true), so I sent a keyboard command:

keyboard "{ctrl+a}" clear

which works, but loses arrow keystrokes occasionaly which is not desirable...


Thanks for your help,
