Is it possible to segment saving of a diagram control so only some controls are saved?

[Brett_Adam]

I have a diagram control with one set of permanent controls, and one set of controls which vary during use.

The permanent controls are editable by users, but only occasionally.

I need to save the permanent controls only, not the variable controls.

Using SaveToStream I get all the controls.

Is it possible to save just one "Layer"?

Variable controls are all of one ancestor class, and this class is not used on the permanent layer. Is it possible to exclude a class-type of objects from the "Save" process?

Or is there a "non-saving" ancestor class I could use?

No, it's not possible. But you can easily do this programmatically by simply removing the variable controls before saving (or after loading).
