Edit Question
Title
Body
Based on the documentation via MSDN... You can also use InvalidateProperty to force re-evaluation of a binding against a data source that is not able to implement the recommended INotifyPropertyChanged notification mechanism... ...the code below should work, yet it doesn't. public partial class Window1 : Window { private Payload _payload = new Payload(); public Window1() { InitializeComponent(); this.DataContext = _payload; } private void Invalidate(object sender, RoutedEventArgs e) { _payload.Timestamp = DateTime.Now.Add(TimeSpan.FromHours(1)).ToLongTimeString(); Button b = sender as Button; b.InvalidateProperty(Button.ContentProperty); } } public class Payload { private String _payload = DateTime.Now.ToLongTimeString(); public String Timestamp { get { return _payload; } set { _payload = value; } } } <Grid> <Button Click="Invalidate" Width="100" Height="50" Content="{Binding Path=Timestamp}"/> </Grid> Any idea what is causing this behavior?
