I didn't say anything about DataSource.Create creating a new record. The documentation states that it effects a save:
"Saves the data from the data controls and clears them afterwards."

Yes, that is how I understood it. It doesn't work.

The record is saved automatically in Gianluigi's project. Perhaps we need a version stripped down that isolates this.

Gianluigi answered that. More specifically, there is an ellipsis button presented when a DataControl handles a blob field. 
Clicking that brings up a "Blob Contents" dialog with "Load", "Save", and "Clear" menu items. I don't know what it is called.
