OLV supports binding columns to data via the Munger class, among others, using anAspectName string that is matched against (public) properties of the row-object's type using reflection. The current implementation does not support explicit interface implementations, which are publically accessable but require scoping to the interface (since multiple interfaces might have different properties that share the same name). This ticket is to add support for these explicit interface implementations, for which I can provide the code if desired. It's isolated to the Munger.SimpleMunger.ResolveName method, except it refactors the existing resolvedPropertyInfo section into a new method for code re-use and performance purposes.
The simpliest implementation is to add support at the end of Munger.SimpleMunger.ResolveName - if no matches are found, continue the search by looking through target.GetType().GetInterfaces()...GetProperties(flags) for a match, identically to how resolvedPropertyInfo is found above.
I think this belongs in Patches or Feature Requests sections, sorry, I was expecting a dropDown then forgot about it.
