I've used Kendo UI since almost the very first release, and the following problem has been there all this time.
From what I see by looking at your .js source code, when using batch/inCell edit mode you already know which model field is being edited when you call the "edit" event, yet you don't give that info to us in the event arguments. Why not? Many, Many times when developers handle the Edit() event in batch/inCell mode, the model field being edited is important to know.
You could very easily pass that to the event. I don't understand why you've let it be this way for so long. Please explain.
