Since we haven't had any reports of problematic behavior for a week after this example, I am going to go ahead and mark this as "Declined". The basic scenario works when implemented correctly by the app, and if the grid were to handle the INotifyPropertyChanged of the collection, it would result in far too many re-renders for good performance and we don't want to do that.

Hi Robert,

The re-render should already happen because the framework monitors the properties and fields. Below is an example of how that works as expected for me. You can also force the grid to update the data as explained in this documentation article: Grid - Refresh Data.

If these don't work for you, please provide some more detail on the problem. At this stage, handling the NotifyPropertyChanged is likely to just add a lot of overhead and deteriorate the performance of the component.
