Now I understand what you have meant in your previous post. This happens because the EmptyContent is displayed when the list box is completely empty. While there is a footer, the list box is not empty and the EmptyContent is not displayed. We will think of a way to extend the current functionality of the EmptyContentDisplayMode property to support your scenario. Until then, I can suggest that you add the empty content to the footer and show it when the ItemsSource is empty.
I hope this helps. I have added Telerik points to your account for reporting this issue. Please, let us know if you have further questions.
