I'm looking to write an App on SharePoint 2013, and I'd like to be able to connect App Parts in the same way you can currently connect Web Parts -- through the connections menu, and ConnectionProvider / ConnectionConsumer attributes.
I can't find any examples or references to tell me whether this is possible, or whether a similar feature exists. Anyone know if this is possible, and if so, what APIs I need to know about?
An example use case; I stick two App Parts on a page; one contains a dropdown; the other contains a table. Changing the value in the dropdown changes the contents of the table.
Can anyone tell me if this is possible?
