注釈
SeekAlignedToLastTick は、 のシークされた時刻を最後の Storyboard クロック ティックに合わせます。 画面が更新されるまで画面にこれらの変更が反映されない場合でも、 による SeekAlignedToLastTick変更を反映するように値が直ちに更新されます。
シーク操作では、ストーリーボードまたはSlipBehavior設定がSpeedRatio考慮されないことに注意してください。 ストーリーボードは、 が 1 で SpeedRatio 、 がない SlipBehaviorかのように扱われます。
このメソッドは、ストーリーボードクロック CurrentState を に変更します。
ストーリーボードをシークすると、 イベントと CurrentStateInvalidated イベントがCurrentGlobalSpeedInvalidatedトリガーされます。
このストーリーボードを対話的に制御するには、ストーリーボードの開始に使用した対話型メソッドを呼び出すときに同じ containingObject
パラメーターを使用する必要があります。 制御可能なストーリーボードは、一時停止、再開、シーク、停止、および削除できます。 コードでストーリーボードを制御できるようにするには、ストーリーボード Begin の メソッドの適切なオーバーロードを使用し、 を指定 true
して制御できるようにする必要があります。 例については、「 方法: 開始後にストーリーボードを制御する」を参照してください。
適用対象
SeekAlignedToLastTick(FrameworkElement, TimeSpan, TimeSeekOrigin)
この Storyboard を新しい位置まで即座 (同期的) にシークします。

SeekAlignedToLastTick は、 のシークされた時刻を最後の Storyboard クロック ティックに合わせます。 画面が更新されるまで画面にこれらの変更が反映されない場合でも、 による SeekAlignedToLastTick変更を反映するように値が直ちに更新されます。
シーク操作では、ストーリーボードまたはSlipBehavior設定がSpeedRatio考慮されないことに注意してください。 ストーリーボードは、 が 1 で SpeedRatio 、 がない SlipBehaviorかのように扱われます。
このメソッドは、ストーリーボードクロック CurrentState を に変更します。
ストーリーボードをシークすると、 イベントと CurrentStateInvalidated イベントがCurrentGlobalSpeedInvalidatedトリガーされます。
このストーリーボードを対話的に制御するには、ストーリーボードの開始に使用した対話型メソッドを呼び出すときに同じ containingObject
パラメーターを使用する必要があります。 制御可能なストーリーボードは、一時停止、再開、シーク、停止、および削除できます。 コードでストーリーボードを制御できるようにするには、ストーリーボード Begin の メソッドの適切なオーバーロードを使用し、 を指定 true
して制御できるようにする必要があります。 例については、「 方法: 開始後にストーリーボードを制御する」を参照してください。
