How to Keep AdditionalContent of Specific RadDiagramShapes Persistently Visible and Customize Styles via MVVM?

[Joey]

Hello Telerik Team,

I'm working with the RadDiagram control and have a scenario where I need certain RadDiagramShapes to display their AdditionalContent persistently – meaning the content should remain visible even when the shape is not selected. Additionally, I want to achieve this behavior and customize the AdditionalContent's styling purely through MVVM binding approaches.

Could you please provide guidance or code examples demonstrating:

1. How to keep AdditionalContent visible for specific shapes regardless of selection state.
2. How to dynamically style AdditionalContent (e.g., colors, templates) using MVVM properties.

Any suggestions for binding strategies or relevant Shape/Style properties would be greatly appreciated. Thank you!
