|Title: Did you know that you can protect a Grid from editing without coding any event?|
When a Grid resource (row, column or cell) has to be protected from editing, it's normal practice to
Despite not beeing wrong, this approach is not optimized especially in a thin client environment, as it generates client/server traffic for the event handling (the UI on the client informs the runtime on the server that an event occurred, the runtime responds that the event should fail and so the UI makes it fail).
So, a code like this (written in the Grid Event Procedure):
evaluate event-type when msg-begin-entry |first two columns are read-only evaluate event-data-1 when 1 set event-action to event-action-fail when 2 set event-action to event-action-fail end-evaluate end-evaluate
Can be changed to:
|first two columns are read-only modify screen-1-gr-1 x = 1, column-protection = 1 modify screen-1-gr-1 x = 2, column-protection = 1
(written in the program Procedure Division, after the DISPLAY of the Grid)
