Hi Trevor.
Actually I came up with a fairly elegant solution which is quite simple. In the
column behavior script I added some code:
on FillInData pData
-- This message is sent when the Data Grid needs to populate
-- this template with the column data. pData is the value to be displayed.

I think at some point the way this needs to work is to send fillInData message
to the script of the datagrid. Most LC devs see the datagrid as a complex
magical black box kind of object, and are reticent to pull it apart or copy
bits of it to other places to get it to do something different.
Hi Trevor.
Just a heads up, I followed those instructions in the lesson to the letter. It
broke my datagrid. It would no longer populate and I could not select a row by
clicking on it.
It may have to do with the new dg behavior heirarchy. I could see that someone
else was having difficulty
Thanks Trevor. I perused the lessons and the documentation but could not find
anything that might aid me in this. I will have a look at that lesson!

Okay, looks like this is a no go. I read from one of the datagrid lessons in
reference to populating the datagrid "by hand":
Important: When using this technique properties like dgData, dgText,
dgDataOfIndex, etc. will no longer return values. The data grid is just
displaying records from
In a table datagrid, can't you edit the column template so that you can control
what goes into the field for that column? I think the underlying data will
remain the same, but what goes into the field is what you put there. I suspect
the datagrid will then sort by the underlying data, not the

There is no way I know of to have a datagrid sort by an invisible column and
still show that it is sorted by a visible one. Every time the datagrid
"redraws" it's going to update the appearance of the header to reflect the
sort.
If you want to force the sort when you populate the datagrid,

Hi all,
given a datagrid (table) with three columns
C1 -> visible
C2 -> visible
C3 -> invisible column
Is it possible to sort a datagrid by column C3, although
the user has clicked the header of column C2.
Know what I mean?
If this is possible, any hints on how to do this are highly
