It's okay, the Data Grid likes to be beta up on once and a while :-)
As long as this is still in Beta, may I make a suggestion?
Sorry, that was supposed to be "beat" not "beta".
:-o))
(Does anyone ever let the possibility of the answer be "no" stop
them?)
I had assumed when I saw the following code in the guide:
put field "data" into tData
put true into pFirstLineContainsHeaders
set the dgText [ pFirstLineContainsHeaders ] of group "DataGrid 2"
to tData
I assumed that the data grid would function in much the same way
that FileMaker does when importing an Excel file, i.e. it allows
one to assign the items in the first line of the file to field
names and the rest of the llines to populate these fields. That
would be a reasonable behavior of
"dgText[pFirstLineContainsHeaders]" il.e. when the parameter is
true, the column headings are taken from the first line of the text
field and the rest go into filling the columns.
I must confess that I interpreted this code in the same way
in particular, I think, because this phrase "If true then the data
grid will extract the first line of pText …"
The first line is only used to tell the data grid which columns to
map the rest of the data to. If you want to create columns then you
will need to set the dgProp["columns"] property.
That's OK for me now, Trevor :-)
Might be nice to elaborate a bit in this lesson to prevent from this
misinterpretation.

You can't really use multiple parameters when using setProp (which
is what dgText is). I'm kind of fudging things a bit by treating
dgText as a custom property set and pFirstLineContainsHeaders as the
custom property. The truth is we still don't have access to a very
expressive syntax when creating custom controls (which the Data Grid
is one).
