I've done this both ways, but I'd like to hear what you guys do....

Bind The Entity
Have the VM get an entity, or pass it in to the CTOR, store the entity to a property on the VM, and bind the View to the entity's properties.

With this approach, the only way to 'undo' is to requery the data, but it's easier to set up and maintin, IMHO.

Bind To VM Properties
Have seperate properties on the VM for everything bound on the View. Load those properties from an entity. Then, when saving, create or update an entity from the VM and save it.

To Undo, simply reload the VM's properties from the entity. But it's another set of properties on the VM mirroring those on the entity.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
