Have Webpart A & B that are derived from AbstractWebpart. Here is the scenario....add and configure several A/B webparts to the page. There is one webpart property that i want to be able to configure one of two ways. Either 1) each webpart can configure the property individually or 2) the user can configure the webparts so that the property is set on a page basis...i.e. if you set the property of one all webparts on the page get set.
I have been thinking about how to do this but am a bit stumped....looking for some guidance from the gurus out there.
