Gets or sets the name of the service field in a data source that contains parent node values. This is a dependency property.
A String value that contains parent node values.
To display data in a tree, a data source should contain two additional fields. The first field must contain unique values. Its name is specified by the TreeListView.KeyFieldName property. The second field must contain values that indicate parent nodes for the current node. Its name is specified by the TreeListView.ParentFieldName property. Columns bound to these fields are called service columns.
The data types of the data source fields specified by the TreeListView.KeyFieldName and TreeListView.ParentFieldName properties, must be the same. These values (key and parent) cannot be equal for a node.
