Is there anyway to determine which interface a webpart uses for connection?
I have a custom web part, implementing the ICellConsumer interface, and I am trying to send values to the SPVisibilityFilter webpart, available here
http://spvisibilitywebpart.codeplex.com, which seems to be implementing the ICellConsumer interface as well.
Yet, I still keep getting "the connection type ' is not compatible with any other web parts on the page", when trying to connect the web parts on the page. What am I missing?
