Binding ObservableCollection to WPF ListBox

Question

I have the below code-behind:

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            


        

Answer 1

Yes, you'll need to set the DataContext somehow. It doesn't have a DataContext, because the Window doesn't have a DataContext unless it is set. The ListBox will get the DataContext if you do this in the constructor.

public MainWindow() 
{ 
    InitializeComponent(); 
    this.DataContext = this;
} 

Otherwise you can use RelativeSource, ElementName etc. in the Binding but I guess you knew that =)
