String that points to the ID of the XML object which has the data that is to be displayed in the tree. |
Remarks
The tree Data contains the data that is to be shown in tree format. Such data should strictly adhere to the definition made in schema of the tree (tree Schema). The source for tree Data can be an XML document or data obtained from a back end database. In the latter case, a busdataisland can also be used as a source for tree.
If the data is to be taken from the busdataisland directly into the tree, then the value for this property would bebusdataislandID.datawhere busdataislandID denotes the unique identifier of the busdataisland from which data is to be taken.
