Thanks for writing and for your interest in RadControls for Windows Phone.
I have tried to reproduce the behavior on my side by setting both the EmptyContent
properties in XAML and didn't manage to reproduce any errors.
Can you please share some code or directly send me the project you are using so that we make sure I have the same set up on my side. This will help me directly debug the case and see how I can help.
Note that in order to be able to attach a project you will have to open a new support ticket.
Thanks for your time.
