How to reference a generic type in the DataType attribute of a DataTemplate?

Question

I have a ViewModel defined like this:

public class LocationTreeViewModel : 
    ObservableCollection, INotifyPropertyChanged
               


        

Answer 1

No, you cannot express a generics type in XAML. You will have to create a concrete type that extends your generic one ...

public class FooLocationTreeViewModel : LocationTreeViewModel
{
}
