I've never used MVVM before, so I'm probably missing something obvious. When I create a new Panorama application, there's already a ViewModel folder containing ItemViewModel and MainViewModel.
I thought "MainViewModel.cs" is the file that organizes the panorama. However, within MainViewModel, it has this line:
public MainViewModel()
{
this.Items = new ObservableCollection<ItemViewModel>();
}
The ItemViewModel has no interaction with the panorama. These are the then instantiated like this:
this.Items.Add(new ItemViewModel()
{ LineOne = "first line", LineTwo = "second line", LineThree = "third line" });
Why isn't ItemViewModel just a 'Model'? It implements INotifyPropertyChanged, but for what purpose? I would've thought that the ObservableCollection in MainViewModel would be enough to notify any changes, as demonstrated here
thanks
