Summary

Indicates if child nodes are stored in the tree, or recreated when the parent node is expanded.

Pascal

 propertyPersistentNode: Boolean;

Description

PersistentNode is a Boolean property that indicates if child nodes are stored in the tree, or recreated when the parent node is expanded. When PersistentNode contains False, collapsing a node causes its' child nodes to be removed from the tree structure. Expanding the node will cause its children to be derived by calling RefreshChild. When PersistentNode contains True, child nodes are unaffected by actions that collapse the parent node.
