Public ReadOnly Property Bookmarks As ObservableCollection(Of DiagramBookmark)

 Property Value

Bookmarks are displayed by the MiniMap control.

At this time, the control does not provide a built-in way to add bookmarks interactively. You can let users create bookmarks from event handlers such as DoubleClicked or from a context menu. Alternatively, you can create bookmarks programmatically to reflect the diagram's contents by calculating them from node and link positions and metadata.
