hey Peter, thanks for your response.
I read the following in the grid documentation
“DataGrid has built-in UI for Dynamically Adding a New Column. To enable it, you need to set the ‘editing.addNewColumn.visible’ property to true.
Press the ‘+’ button to open the ‘New Column Dialog’. On open and close, the ‘openColumnDialog’ and ‘closeColumnDialog’ events are fired.”
How can I listen to those events?
