2 개의 시각적 상태가 정의 된 Silverlight 4 응용 프로그램에 ChildWindow가 있습니다.VisualStateManager.GotoState가 ChildWindow 내에서 작동하지 않습니다.
시각적 상태는 내가 블렌드에서 미리보기를 원하지만 ViewStateManager.GotoState를 호출하면 false를 반환하고 시각적 상태가 전환되지 않습니다.
Heres my XAML. 길이에 대한 Appologies ...

VisualStateHelper.VisualStateName은 값이 변경 될 때 VisualStateManager를 호출 바로 연결된 속성입니다. 이 속성의 구현은 다른 곳에서 작동하므로 문제가되지 않을 수도 있습니다.
private static void OnVisualStateNameChanged(object sender, DependencyPropertyChangedEventArgs args)
{
var visualStateName = (string)args.NewValue;
var control = sender as Control;
if (control == null)
{
throw new ArgumentException(Resources.VisualStateHelperSenderNotAControlErrorMessage, "sender");
}
VisualStateManager.GoToState(control, visualStateName, true);
}
