TreeNodeControl

The TreeNodeControls are Data Source-based controls. By default, they contain a number of EventListeners and scripts.

TreeNodeControls can only be contained in a TreeControl. TreeNodeControls can only contain EventListeners and scripts. The main properties of the TreeNodeControls are listed in the following table:

Name	Description
Data Source Name	Name of the referred DataSource
Data Source Item	Name of the referred DataSource item
Child Nodes	List of TreeNodeControl names that act as its child nodes
Image	URL for the image of this node. Default is images/folder.png

The Data Source Name and the Data Source Item properties bind the node to the data. The following figure illustrates their relationship:

WD_help0053

In this figure, the TreeControl has one root node: Schoolyear. This node is bound to 'DOCTREE_SCHOOLYEAR/SCHOOLYEAR_LABEL'. It has one child node: GoverningBody.

GoverningBody is bound to 'DOCTREE_GOVERNING_BODY/GOVERNING_BODY_LABEL'. This process is repeated for the other nodes.

The child nodes are related to their parent nodes with a Run Time Relate. This is a standard Relate object, except that the property Synchronization DataSource is left empty.
