title: iterate through an existing observable collection gathering 2 of the properties in said classes c#
body: <p>currently im using an observable collection called locationItems to to store my objects from a locations class.</p>
  
  <p>on the page im working on i currently pass one object via selected index from the last page.
  DataContext = App.ViewModel.LocationItems[index];</p>
  
  <p>I would however like an option to iterate through all of the items in that ObservableCollection LocationItems { get; private set; } so that i can gather values from its objects created and plot them on a map.</p>
  
  <p>so how do iterate through these ?? </p>
