Syntax

Procedure OnSetCalculatedValue ByRef String sValue

Description

If there is no data binding (no Entry_Item command) but the data entry object (DEO) is served by a DataDictionary object (DDO) Server, then the DEO is a calculated value. The initial data is filled by sending the OnSetCalculatedValue event.

This is fired whenever the DDO performs a Find, Clear or Delete operation.
