<Calendar Name="calendar1" Loaded="calendar1_Loaded"/>

The following example shows the Loaded event handler. The event handler calls the AddDatesInPast method to make only future dates selectable.

private void calendar1_Loaded(object sender, RoutedEventArgs e)
{
    Calendar cal = sender as Calendar;
    cal.BlackoutDates.AddDatesInPast();
}

Private Sub calendar1_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs)
    Dim cal = TryCast(sender, Calendar)
    cal.BlackoutDates.AddDatesInPast()
End Sub

Remarks

Use this method to prevent users from selecting dates that are in the past.
