Property Value

Type: System..::.Int32
The unique identifier for this element.

PersistId uniquely identifies each element. An element keeps the same PersistId every time the same Extensible Application Markup Language (XAML) is loaded (including binary representations). This identifier is used for internal loading, parsing and serialization requirements. It is not intended to be used by your application code.

This property has no relationship to the GetHashCode result for any given instance.
