I've seen lots of talk about this question but maybe I'm just too much of a newbie to get it. If I have an observable collection that is a collection of "PersonNames" as in the msdn example (http: //msdn.microsoft.com/en-us/library/ms748365.aspx), I get updates to my View if a
PersonName is added or removed, etc. I want to get an update to my View when I change a property in the
PersonName as well. Like if I change the first name. I can implement
OnPropertyChanged for each property and have this class derive from
INotifyPropertyChanged and that seems to get called as expected.
My question is, how does the View get the updated data from the
ObservableCollection as the property changed does not cause any event for the
This is probably something really simple but why I can't seem to find an example surprises me. Can anyone shed any light on this for me or have any pointers to examples I would greatly appreciate it. We have this scenario in multiple places in our current WPF app and are struggling with figuring it out.
"Generally, the code responsible for displaying the data adds a
PropertyChanged event handler to each object currently displayed onscreen."
Could someone please give me an example of what this means? My View binds to my
ViewModel which has a
ObservableCollection. This collection is made up of a
RowViewModel which has properties that support the
PropertiesChanged event. But I can't figure out how to make the collection update itself so my view will be updated.
