The ISNODECOLUMN attribute specifies the form field that indicates whether a tree node has children.


ISNODECOLUMN = column-name
  1. column-name is a form field name.


This attribute is used in the definition of a TREE container, to specify the name of the form field indicating whether a tree node has children.

Even if the program node does not contain child nodes for this tree node, this attribute may be used, to implement dynamic filling of tree views.

You must specify form field column names, not item tag identifiers.

This attribute is optional.
