Hi all,
After much fiddling with the code and looking into the depths of LC core
code I've found what happens, and it's all to do with message flow.
This way works as expected:
1. I create an array from Data
2. Apply data to DataGrid using set dgData
3. Read from data in the same handler or sub
Thanks Bob, but the columns are defined, both in my test stack and the
project stack. It gets filled once the scripts have finished running, so it
can't be that which is the issue in this instance. But thanks once again
for your input.

DGText will only contain data for the columns you have defined in the Datagrid
properties. If your dgData array keys have no matching columns it will still
populate the dgData but dgText will return empty. This is why I avoid using
dgText at all anymore.
I have also noticed that if one of the
I’ve tried using wait, wait with messages, wait until. No joy.
But in a separate test stack with the same data it works just fine having
them one after the other.
There is no sense to it NOT passing the text one line to the next.
I thought it might be because it was located in a preOpenCard
The difference between the working and non-working examples seems to be
limited to the introduction of a delay in the working one, between
setting the dgData array and later obtaining its text.
Since the array form is what the DG uses internally, perhaps something
during loading of that array
Thanks Craig
This could make some sense. There are a lot of handlers to deal with. I
thought I was going a bit mad. I’m just going to have to pick my way
through.

I have seen this here and there for years, and having nothing to do with
dataGrids per se.
A handler will fail to run, but will step through in the debugger without
issue. This usually resolves, and I never know why.

Hi All
This has been a bit of a mind bender, mainly because in a test stack it works
just fine, but...
Has anyone ever had problems with something like this:
on myHandle
— ...some code
Set the dgData of grp “myDG” to tDataA
Put the dgText of grp “myDG” into tDataS
— tDataS returns empty
