"Semi-persistent" Fields |
Sun, Apr 9 2006 12:31 PM | Permanent Link |
Heiko Knuettel | Just a thought :
I'd love to have fields that behave like a hybrid of persistent fields and calculated fields. Treated by Delphi like persistent fields, so you can edit/post in every DBaware control, but stored only temporarily in memory, not saved to the database, initialized with nulls on dataset.open and dumped on dataset.close . Would be great to store temporary information like is-this-row-selected without having to copy the whole table into memory, and also great to process user input in DBAware controls without using OnGetText/OnSetText. What do you think ? Cheers, Heiko Knuettel |

Good idea. You can do that right now with canned queries, but I think it's complicated to add it for TDBISAMTable. Ralf |
