I have a listbox and I want its ItemsSource to be all the items of an ObservableCollection + an additional static text such as "All Items."
Right now I just have something similar to:
listbox1.ItemsSource = from Car c in Cars
select c.Model
I know I could just manually add the text to the listbox, but I want it to be part of the query because the linq query is bound using the Obtics library (so the UI updates reactively). I am not too familiar with linq queries outside the basics, so does anyone know if this is possible? Thanks
