I'm playing around with the developer example projects for the gridview, specifically the "ComboboxColumnItemsSourceBinding", and I enabled the Search Panel on the Gridview where FilterMemberPath is set, but noticed it doesn't search inside the ComboBox Column. If I type for "Webber" in the Search Panel it comes up with nothing.....but the filter control for that column will work.
Is there something I am missing in the demo that I need to add to get this functionality working? Or do I need to go as far as making my own predicate and use FilterDescriptor<T>?
