>Got a Calendar class (RCSCalendar.vcx) and a TextBox to hold the selected date. The class has 42 small labels and on the click event (inherited from their parent labels) they populate a property on the container. I want to update the TextBox whenever that click occurs. It doesn't seem correct to add code to all those parent label Click events to refresh the TextBox value as it is at the form-level, as is the container, but I'm not sure how to get the TextBox to refresh other than in those 42 Click events. It's much simpler than I made it sound, but I can't think of another way to say it.

If you can modify the class, you can add a assign method to the property of the container and in it put something like this.parent.refresh()

[Update]
And if you can not modify the class you can use a bindevent(YourCalendar, 'PropertyThatIsUpdated', YourCalendar.Parent, 'Refresh') or similar
