I'm looking for a way to find out whether an editing session for an entity is open (if BeginEdit has been called)? I looked at EntityAspect and EntityState and didn't see anything. It looks like I can override Entity.BeginEditCore, Entity.EndEditCore and Entity.CancelEditCore to implement something if needed.

You could always check to see if EntityVersion.Default is the same as  EntityVersion.Proposed; until an editing session is started, it will instead be mapped to EntityVersion.Current. It might be easier to implement a new property as you've suggested, though, since it gives you one clear place to check.

Yours,
Robert

Actually, I've just realized that if you ask for EntityVersion.Proposed, when it hasn't been defined by starting an edit, you'll get EntityVersion.Default (which in that case will be EntityVersion.Current). Checking this clearly won't work, you'll have to implement what you suggested.
 
Sorry for the wrong information. It made sense, but it didn't seem to be working correctly when I tried it out, and when I checked teh documentation, I saw that I'd forgotten how EntityVersion handles undefined versions.
 
Yours,
Robert

OK. Thanks very much, I'll set a flag in my object.
