Отсутствует плитка в Telerik TileList

Question

У меня 14 плиток в моем TileList (Telerik). Однако только 11 из них показаны на странице. По какой-то причине я не могу использовать пространство в правом нижнем углу области. Любая идея, почему это может вызвать эту проблему?

Answer 1

решаемая. Причина была в RadPersistenceManager. Он загружал состояние, которое было сохранено на 3 строки в Page_Load. Я изменил сохраненное состояние.
