Как сделать чтобы изменения поля отображались сразу

[Russland]

myTable_ds.research(); должно помочь. Т.е. необходимо обновить источник данных формы

Refresh: Refreshes the screen (current record), without accessing the
database. RefreshEx(int n): To refresh the data according to parameter "n".
ReRead: Re read the current record and updates the screen.
ReSearch: Uses the current query clear the grid, and reread all records.
ExecuteQuery: Builds the query, including resetting user sorting etc, and
uses research to show the result.

If you want to refresh the form with records that were inserted in a method
or job that was called, then you should use research.
