AsInfo

property AsInfo: string read write

Example

procedure ScriptEvent(var Value: variant);
begin
  Value := Field.AsInfo;
end;

Usage

AsInfo formats DisplayName plus AsString when read but writes the complete assigned text directly to AsString.

Asymmetric setter

The setter is not an inverse parser. It writes the entire supplied string directly to AsString:

AsString := Value;

Assigning a value previously returned by the getter therefore attempts to store text such as Customer code: ABC in the field. It does not remove the label or colon and can corrupt string data or cause conversion failure on numeric/date fields. Treat AsInfo as read-only diagnostic formatting in scripts even though Velox scripting registers a setter.

Reading uses the field's normal string conversion. Assignment follows normal dataset edit, read-only, conversion and validation rules, changes only the current record and does not post or commit. Field labels may contain sensitive schema information; apply normal logging controls.

Additional Technical Info

The AsInfo getter produces a labelled diagnostic string:

DisplayName + ': ' + AsString

DisplayName is normally the field's display label or field name. The value portion uses AsString, not DisplayText; display formatting or an OnGetText presentation can therefore differ from other UI output. A null value normally contributes an empty string, leaving the label and colon.
