QUESTION
I am creating a subclass of ContentView, UserPostView
to use as a data template in a ListView. I dynamically add items to the ItemSource of ListView by creating new instances of UserPostView
.
ANSWER
Answered 2018-Apr-20 at 14:46If you could provide your ListView's xaml and DataTemplate we could provide you with a better answer.
However, my guess is your ListView's ItemsSource
should be set to a List of ViewModel : INotifyPropertyChanged
with your properties on it instead of on your ContentView and your ContentView should be bound to that ViewModel. For example:
