Thanks Arnd and Olan

I'll try those options.   My preference will be to update the concerned rows instead of complete retrieve.  As Arnd pointed out there may be more view window(s) and edit window(s) open at a point.  Need to find way(s) to rightly update the concerned view window, as there is a possibility of the same view window opened multiple times (as instances).  

Another way to refresh a window COMPLETELY is to POST a call to the Retrieve event being used, or to the OPEN event if that calls more than one Retrieve event.

And of course you can always define a new event to specifically re-retrieve the DWs in your object, then POST your call to that event.


Good Luck,

Olan

1. ) ReSelectRow() is your friend (https://docs.appeon.com/pb2019/datawindow_reference/ch09s121.html)

2.) Depends on your application framework.
Your edit windows needs to call a method so that the datawindow in the list knows which row has to be retrieved.

If the edit window is a response dialog, that should be easy.

If there can be multiple edit windows you have to setup some message logic to inform the list about changes. You have to find attributes (often the PrimaryKey) to identify the rows that have to be retrieved/refreshed.

To remove rows form the list window, you can use RowsDiscard (https://docs.appeon.com/pb2019/datawindow_reference/ch09s130.html).
