So basically, what I'm trying to achieve here is to have the grid update dynamically when the underlying data changes.
After more extensive research, it seems that one of the causes of this issue is that the ObservableCollection doesn't implement the INotifyPropertyChanged interface. It notifies on when items are added/removed, etc. but not when an item's property has been modified. It was suggested by Jenny from Xceed that a BindingList could be used instead.
Although I've found this information, I'm still not really any closer to solving my problem. Because of performance issues, I've had to disable data virtualization, and my cell background and stuff are pretty much set only on the "realization" of the cells.
