I read all the doc and Q&A I could find, but can not figure out how to change the appearance of the green, dashed rectangle that appears when the user selects a shape in a WinForms diagram.

View > InteractiveAppearance > SelectedStrokeStyle
changes the appearance of the shape itself, not the bounding box.

Shape > InteractionStyle > Bounds = false
hide the bounding box but I want to change its stroke and color, not hide it

Which object properties do I change to change the appearance of the selected shapes bounding box?

Thanks very much in advance,
