Hi, I trying to use IUniqueValueRenderer.get_Symbol(value) . The reference says to pass the value when there's no grouping. When there's grouping, you pass the reference value. How do you find out if values are grouped or not?
I tried to use IUniqueValueRenderer.get_ReferenceValue(value), thinking it would return null when there's no grouping, but it actually throws an exception.
I guess I could catch the exception and use that to indicate whether there's grouping or not, but that's an inappropriate use of an exception.
suggestions?
