Description
Variant
A VARIANT expression that defines the extra-data associated with the element.
By default, the element's UserData property is empty, so no
extra-data is associated with the node. You can use the UserData property to
associate your extra data with the current element. The UserData property is
not used by the control in any other way, it is provided to store your extra
data.
