HOW TO：在腳本開始後使用事件觸發程式進行控制
更新：2007 年 11 月
本範例說明如何在 Storyboard 啟動後加以控制。若要使用 XAML 來啟動 Storyboard，請使用 BeginStoryboard，它會將動畫散發至顯示為動畫的物件和屬性，並接著啟動腳本。如果您藉由指定 BeginStoryboard 的 Name 屬性來指派名稱，它就會成為可控制的腳本。在腳本啟動後，您就可以用互動方式控制腳本。
您可以將下列腳本動作與 EventTrigger 物件搭配使用，以控制腳本。
PauseStoryboard：暫停腳本。
ResumeStoryboard：繼續暫停的腳本。
SetStoryboardSpeedRatio：變更腳本速度。
SkipStoryboardToFill：讓腳本前進至填滿期間結尾 (如果有的話)。
StopStoryboard：停止腳本。
RemoveStoryboard：移除腳本，因而釋放資源。

下列範例使用可控制的腳本動作以互動方式控制腳本。
