2つ必要ですStoryboards
。
1つはスライドアウトを実行し、もう1つはスライドインを実行します。
コントロール内では、Expander
が必要になりToggleButton
ます。これToggleButton
がChecked
の場合、スライドアウトアニメーションを起動し、の場合Unchecked
、スライドインアニメーションを起動します。
アップデート
私は個人的にこのタイプのアニメーションをコントロールのスタイル内で実行することを好みます。そのため、コードを複製する必要はなく、簡単に共有できます。
ここで行ったことは、Expander
デフォルトのスタイルに基づいて新しいスタイルを作成したことです。
スタイル内で、ExpandSite
常にになるように設定し、に設定されているときにVisible
作成されたコードを削除しました。また、スライドアウトとスライドインのアニメーションを処理する2つのストーリーボードを作成しました。ExpandSite
Visible
IsExpanded
True
スライドアウトアニメーション(つまりExpandAnimation
)では、最初にofをに設定してからVisibility
、ExpandSite
;をVisible
アニメーション化します。スライドインアニメーション(つまり)で、最初のアニメーションを作成し、を最後に設定ScaleX
します。CollapseAnimation
ScaleX
Visibility
Collapsed
