If my DataSource is a simple List<T> and I edit a cell, is it supposed to automatically update the item at the existing List<T>, or should I modify it inside an OnChange event code?
My row objects have {get; set;} and I see that get; is called when the grid is initially rendered, but set; is not called when I edit a cell.
The important thing here is that OnEndEdit handler should be there in order to get what’s edited by the user. Then you can use different options to send this information to the backend. In our help tutorial, we demonstrated a popular one.
