Do you have an example of databinding for GroupDescriptorsSource from xaml? Or is it not meant to be bound that way?
edit: I changed my source to an ObservableCollection and the exception went away. The docs show using List<> which doesn't seem to work.

Hi Derek,
Thanks for writing and for your question.
In general, you should be able to use any type of IEnumerable<DataDescriptor> to bind the GroupDescriptorsSource, SortDescriptorsSource and FilterDescriptorsSource properties. However, I have discovered a small issue related to casting to a wrong type which causes the undesired behavior you have experienced. We will fix this. The workaround you have found in the meantime is completely OK and you can use it in your app.
I have updated your account with 1000 Telerik points for bringing our attention to this issue.
