For batch mode (inCell editing), when a value is changed in a cell, is there an event that can be used where I can know what field changed and what the previous value was?
I asked about this several years ago, so I'm asking now again in 2017 hoping you have an answer.

I already know about the dataSource change event, which will tell me which field changed and what the new value is, but I need the previous value, without the need for a custom editor.

Hello Curt,
Within the save event of the Grid you can get reference to the new value and the old value. The new value is accessible within the values collection of the event argument and the old value is within the model:
Hope this helps.

OK, thanks, that works. I read the documenation for the grid's save event, but because you don't say that the model passed to the event is the old or the updated version (with the new values), I assumed it was already updated when it's passed to the save event. It would be greatly helpful if you would not assume we know what you mean when we read the documentation for that event. It would be very helpful if you would update the wording for the e.model to say that this instance of the model data is **BEFORE** the new values have been applied.

Also, where are the properties for the e.values object (like "name") documented?

Disregard my question about the properties of e.values being documented...I see that e.values is an object of all your model properties that changed.
