I am trying to add items to a ComboBox (say Name="labelComboBox") at runtime when I pressed an add button (say with Name="add2labels" Click="add2labels_Click"). But the ComboBox cannot show the values I newly added. What did I miss?
The following is the event handler for the add button:
private List<String> labels = new List<String>();
private void add2labels_Click(object sender, RoutedEventArgs e)
labelComboBox.ItemsSource = labels;
P.S. I am pretty sure the values were added to List<String> labels correctly (its count did increase each time).
