I'm trying to create a custom web part that consumes from an OOTB list view web part's "Send Row of Data To" producer. The list has a lookup field to another list, and I need that value (the associated item in that other list) as a parameter in my custom web part.
Resources I've looked through:
What provider interface does the OOTB list view web part use?
IRowProvider looked like a candidate, but it's listed as obsolete.
Hopefully, once I know what interface is being used, I can find the api and figure out how to drill into the row's data.
