I had thought there had been some work on that in recent years, but I
dug up the bug report and it seems it's been "hibernated":

Maximum length of a LINE in a field:
65,536 characters storage
No more than 32,786 pixels wide for display

Not that this couldn't be worked around, but isn't a field limited in the

That makes sense. Anyone working with this much data should probably build in
their own limits into the data they put into the grid. I know I will.

I read it. :-) My original question was simply, how many columns can a datagrid
have? In other words is there a limit? The reason it mattered to me at the time
was because I was importing a csv file with a lot of columns and it was easier
for me to set the dgProp ["columns"] to the first line
The limit of LC is not the sky but the 65535-limit
for coordinates of every object.
A line width can't be longer than 65535 pixels.
And if you have columns with a width of 11 pixels
each, then the right of column 5958 is 65538 what
is "off-limits".

All:
It is certainly possible that one might need an enormous DG or table field.
It never happens that one must view such a beast all at once, or even a
large part of it; that is not the issue. The point is that one cannot have
such a control at all, and that seems unfair.
If one is looking at
For me the issue was converting a csv file exported from a copier. The csv file
has a LOT of columns (page counts for virtually everything and paper type black
and color the copier is capable, including scans, fax etc.) In the end I
decided to not use that file format and instead use the
That wasn't the issue. The issue was, how many columns before noticeable
decline in performance, and eventually death for the datagrid.

I don't remember what-all he did with it, but FileMaker proved to be
remarkably resilient pretty much no matter what he threw at it. The one
limitation back then was that a given file couldn't be more than 32MB(!).
