Of course they have a data dictionary which holds the caption information an much more about each field, the builders use this info to populated all this data like:
Yeah, we have had these discussions on the forum, and we may provide this type of functionality in the future, but it will not be stored in the database. If you have noticed, we have 3 methods of pulling localization, SQL Server, external XML, and embedded XML. The embedded XML is by far the fastest...so this would be the type of implementation that the data dictionary logic would follow. Pulling all of this type of information from a server, especially in a disconnected data environment, would be application suicide 
To make this fast it would all have to be embedded on the client side...just like we did with the localization.
TIP! I know of another popular .NET framework which has this kind of builder to populate all controls in the form and there is not need to go to every control to do the BindingField manually.
Edhy, the current version of StrataFrame is NOT the last version. We have gathered many good ideas that we fully intend to implement in StrataFrame. We have MANY things that we intend to add to StrataFrame...but this is not a feature that we have today. If all software companies could come up with every idea and create the perfect software to last the ages the very first (or many) blush, then there wouldn't be maintenance releases and the "next" release. I think that you get my point. We plan to have many new RAD features in the future, but this particular feature that you want is not currently there....I am aware of what you want and it is on the list of future enhancements.
