Updating Appointments in backgroundworker

[Cameron]

Hey,

I am trying to get my appointments to update in a backgroundworker. I have the backgroundworker up and running but when I assign my appointments to the ObservableCollection on the viewmodel  in the RunWorkerCompleted and fire the NofityPropertyChanged I get an error "Must create DependencySource on same Thread as the DependencyObject." I do not get this error when notifying of changes to strings and ints. Do you know of any reasons why the NotifyPropertyChanged would not work. 

 Thanks

Hi Cameron,

What I can suggest you would be to check how our BusyIndicator First Look example is implemented (it loads the ScheduleView appointments through a BackgroundWorker):
http://demos.telerik.com/silverlight/#BusyIndicator/FirstLook

As for the exception you check the answers of the following forums and see if the proposed solutions will help.
