Add a button in your project with this script:

put the behavior of the dgProps["row template"] of grp "myDatagrid"

where myDatagrid is the name of your datagrid.

What is the result in the message box?

The datagrid is a complex group using simple Livecode controls and
custom properties. There is no specific interaction while debugging.

Sorting a datagrid with the "SortDataByKey" works pretty well. The
only problem I got is with carriage returns in the data sorted.
However that was fixed months ago.
