Hi,$0$0$0$0I place a Rotator element on my winform.$0$0Then, using properties window (Items), I add a RadItemsContainer.$0$0$0$0$0Under the RadItemsContainer properties I add any element, for example a RadCheckboxElement.$0$0$0$0$0Doing that results in a message "Object reference not set to an instance of an object". $0$0$0$0$0Any thoughts?$0
