How do I programmatically determine if a layer is versioned?

[GenaroGarcia]

I need to determine if a layer is versioned or not programmatically.
Based on that, I need to set the editing option, "Edit a version of the database with the ability to undo or redo." to true (checked) or false (unchecked).

Is there a way to do this?

Any help is greatly appreciated.

Genaro,

You can tell if an object is registered as version by using the members on IVersionedObject3
Also see this thread: : How to tell if feature class is registered with Move Edits To Base

You can set the versioning options (Editor options versioning tab) via the members on IEditProperties3

Yes, that's what I needed to determine if the editing feature class is versioned or not.

Based on that, is there a way to set the edit session to versioned or not versioned.
I'm switching between layers, one versioned and the other is not.

Yes, use IEditProperties3.MultiuserEditSessionMode to switch  between versioned and non-versioned editing. This is the property behind that checkbox. This can only be set outside an edit session.
