Learning some great properties about CollectionView Now, we’ll build the CollectionView in our XAML. Add the BindingContext with the ViewModel above: BindingContext = new ViewModels.StudentsViewModel() Public ObservableCollection students įinally, we will create a CollectionView, where we will reflect the data structure worked on in the previous steps. Now, we are going to create the student ViewModel, where we will fill it using mockup data to later be able to present it in our CollectionView.
