silverlight-5.0

The interface: public interface IConfigurationsRepository { string this[string key] { get; } } The implementation:

问题 I'm using a Panorama control on a WP7 design, and I want to know if there's some way to deactivate the circular (or round) navigation on it? Basically what I would is to end the horizontal scrolling to right on the last item and vice-versa. 回答1: Even if it was possible, such app would most likely get rejected at Marketplace review.
