Title Body

There seem to be two main ways to define DataContext in WPF: either in code like this: App.xaml.cs (taken from the WPF MVVM Toolkit template ): public partial class App : Application { private void OnStartup(object sender, StartupEventArgs e) { // Create the ViewModel and expose it using the View's DataContext MainView mainView = new MainView(); MainViewModel mainViewModel = new MainViewModel(); mainViewModel.LoadCustomers("c:\\testdata2\\Customers.xml"); mainView.DataContext = mainViewModel; mainView.Show(); } } or in XAML like this: Window1.xaml: <DockPanel> <StackPanel HorizontalAlignment="Left" DockPanel.Dock="Top" Orientation="Horizontal"> <StackPanel.DataContext> <local:CustomerViewModel /> </StackPanel.DataContext> <TextBlock Text="{Binding Path=FirstName}" /> <TextBlock Text=" " /> <TextBlock Text="{Binding Path=LastName}" /> </StackPanel> <StackPanel HorizontalAlignment="Left" VerticalAlignment="top" DockPanel.Dock="Top" Orientation="Horizontal"> <ListBox ItemsSource="{Binding Source={StaticResource FileNames}}" /> </StackPanel> <StackPanel HorizontalAlignment="Left" VerticalAlignment="top" DockPanel.Dock="Top" Orientation="Horizontal"> <ComboBox ItemsSource="{Binding Source={StaticResource Directories}}" SelectedIndex="0" /> </StackPanel> <StackPanel HorizontalAlignment="Left" VerticalAlignment="top" DockPanel.Dock="Top" Orientation
