Binding problems in DataTrigger
In Josh Smith's article,["WPF Apps With The Model-View-ViewModel Design Pattern"][1]

In the code from  AllCustomersView.xaml:

      <DataTrigger Binding="{Binding Path=Name}" Value="True">
          <Setter TargetName="txt" Property="Text" Value="Company" />
      </DataTrigger>

I couldn't find out where the property--Name is. 
I thought it was in the CustomerViewModel.cs.
But indeed it wasn't. How could I know the path of Name?
