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".
(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.
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.
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).
