TProperty.Root Property
Contains a reference to the root object that owns the object instance.
Remarks
Root contains the component container of the object instance holding the property. The Root property is used for some specific tasks, like for example, if the property is an object property (a DataSource property, for example), then Root is used to find the data source reference which was assigned using only the datasource name. Usually the Root property is the form which contains the components being inspected.
