DataWindowChild object

Objects and Controls
System Object Properties, Events, and Functions

A DataWindowChild object is a nested report or a DropDownDataWindow within a DataWindow object. For example, a DataWindow object that populates a column having the DropDownDataWindow edit style is a DataWindowChild object.

The DataWindowChild object is used for accessing DataWindow objects independently from DataWindow functionality, and it inherits from the system Structure object because it needs storage and autoinstantiation.

A DataWindowChild object has no events.

Obsolete functions

Several DataWindowChild functions are described as obsolete, which means that although the functions operate as usual in this release, they will be removed in a future release. You should replace all use of these functions as soon as possible.
