Datagrid internal error

[Ralph DiMola]

Paul,

The max height of a field is 32,767 pixels. This can be hard to quantify
especially on mobile with the cornucopia of screen resolutions. I would
imagine that this limit also applies to groups as well. I got bit on this
when the app worked in the IDE but failed on some devices.

For example, some information from the customer suggest they are working
with a VERY large dataset, so the length of the list in TColumnNames could
be quit long - perhaps hundreds of lines. Is there a practical limit on the
number of columns a Datagrid can be set to?
