How to preserve style for the newly created objects at runtime?
In UWP Diagram, we do not have support to apply common style in XAML for diagramming elements. So, the sample level code is expected to apply style for the newly created objects during runtime interactions like duplicate, drag drop, and drawing tools.
The following are the two ways to achieve this common style.
- By creating the custom class for diagramming elements.
- By using the ItemAdded event
By creating the custom class for diagramming elements
Custom class for diagramming elements can be created by deriving it from its respective view model or implementing the respective interfaces. You can assign the default style for Node, Connector, Port and Annotation in the constructor in respective custom classes.
Refer to the following sample for the diagramming elements default style with custom class.

By using the ItemAdded event
Diagram have support to notify when elements get added in the Diagram by using the ItemAdded event. With the assistance of the ItemAddedEventArgs, validate the elements and assign a default style.
Refer to the following sample for the diagramming elements default style with an item added event.
