I'm glad I could help and nice catch... 
I updated it for clarity.

Thanks - thus far it looks like this has solved the issue, just doing some more testing but looking good thus far (aside from the typos mixing up LastUpdated and UpdateTracker).

Hi Delta_Rich,
 
If you are simply looking for the highest UpdateTracker value, try:
 
var LastUpdated = CriticalEvents.Max(CriticalEvent => CriticalEvent.UpdateTracker);
 
Or if you want to retrieve the CriticalEvent entity with the highest UpdateTracker value, then try:
 
var LastUpdated = CriticalEvents.Where(CriticalEvent => CriticalEvent.UpdateTracker == CriticalEvents.Max(cEvent => cEvent.UpdateTracker)).First();
 
Regards,
   Silvio.

Once my ObservableCollection finishes loading, I wish to find out what the
Maximum value of one of the elements is.

I have used the Max() function but it does not seem to reporting the correct item

e.g. My collection is CriticalEvents and the element I am trying to get is
UpdateTracker (which is a decimal) the code thus goes like this:
LastUpdated = CriticalEvents.Max().UpdateTracker;

It does indeed return a value but it is not the maximum value of UpdateTracker
in this is collection (more like middle of the collection).

Can you please advise me of what assumption I have made that is incorrect and how to solve this issue?
