So there is an example of sorting in the PolyGrid documentation under
the entry for the MESSAGE "headerClick" and under the entry to the
PROPERTY "text" (and in 'the text of me')
The example code only sort the visible rows as "the text of widget X"
returns the data of PolyGrid X as tab delimited, WITHOUT the column
headers, but ONLY the visible rows.
So, what to use for sorting all the data in a PolyGrid by a particular
column?
The tsvData of widget X (and csvData, and Text) doesn't seem to work.
The all seems to only get the visible data (rows). Only the pgData of
widget return the whole dataset of the PolyGrid. Is this the way these
properties are supposed to work?
If that is how text, csvData, and tsvData are supposed to work
(returning only the visible rows), then the sort example in the PolyGrid
documentation require updating otherwise these properties require updating!

So, I bought the Summer Bundle. Yes, it is a good deal.
In my case it was primarily for the Polygrid widget. Our application
uses a Datagrid to display customer research data. The columns headers
are text and the left most column ROWs are test and all other cells
are numbers. Some customers can have quite large data sets and I have
been running into the number of columns (ad a default width of 100px
per column) exceeding a GROUPs 32,767px width maximum (about 327-328
columns). At this point the Datagrid just fails - no data is displayed.
I can now attest that a Polygrid (under LC 9.6.8) does not have this
limit. I have a "test" stack (for Datagrid testing) I converted to the
Polygrid and can easily generate 1000 columns x 1000 rows of data and
it works.
So I guess the answer to bug
https://quality.livecode.com/show_bug.cgi?id=23875 is "Use the PolyGrid"
On that note, the Datagrid has 2 features I use in this specific case,
user column resizing (built into the Polygrid - Yea!) and column
sorting (NOT built into the Polygrid - Boo!). So, does anyone have
some column sort code for the Polygrid they have written that they
might be willing to share?
Also, I have filled a Polygrid enhancement request to allow the left
column (or the left N columns) to be locked/frozen, so they remain
visible when the Polygrid is scrolled horizontally. See
https://quality.livecode.com/show_bug.cgi?id=23880. If you might
benefit from this enhancement, please follow the bug or add a comment
to that effect.
