Question

I have a WPF user contol, in which I have a StackPanel. To this panel I’m adding programatically a label this way (Container is the name of StackPanel):

public void Insert(string Value)
{
     Label l = new Label();
     l.Content = Value;
     Container.Children.Add(l);
}

Now I want to provide some public event SelectedIndexChange, when user clicks on label. Now I have a problem how determine which label was clicked. Can someone help?

If in Insert you add the line:

l.Click += ClickHandler;

then the first argument of ClickHandler will be the control that raised the Click event.

e.g. If your handler is:

private void ClickHandler(object sender, RoutedEventArgs e){...};

then sender will be the label that was clicked.

You could alternatively look at e.OriginalSource.
