I\'m trying to bind a TextBlock to a specific element in an ObservableCollection. This is what I do right now:
private ObservableCollection arr
ObservableCollections do not propagate changes to values stored within objects that belong to the collection. It only fires off the notifications when the content of the collection itself changes (ie. item added, removed, reordered). If you want to make it so that your UI updates when values within the collection changes then you'll have to wire that up yourself separately.
