I have a RadGridView that I am trying to put a custom filter on. The field that I am trying to put the filter on is actually a List<string> field that I am formatting into a comma delimited list with a Converter object. If I have it set up that way, the RadGridView refuses to accept the CompositeFilterDescriptor object (using the Contains operator), but if I format the List<> to a comma delimited string before populating the GridView and forgo the Converter, it works fine.
Is there anything special you have to do when the field is a List<> or is it possible at all?
