備註

每當手指、手寫筆或類似的指向裝置按下並保留在物件上時，就會傳送 保留 事件。

一旦經過短時間臨界值，事件就會以Started類型的HoldingState傳送。

當裝置在保留事件) 之後 (，則會以Completed類型的HoldingState傳送另一個Holding事件。

如果使用者在啟動保留之後取消保留，但在完成之前，會以Canceled類型的HoldState傳送Hold事件。

建構函式

HoldingRoutedEventArgs()

初始化 HoldingRoutedEventArgs 類別的新實例。

屬性

Handled	取得或設定值，這個值會將路由事件標示為已處理。 true的值 Handled 可防止事件路由上的大部分處理常式再次處理相同的事件。
HoldingState	取得互動的基礎 HoldingState 。
OriginalSource	取得引發事件之 物件的參考。 這通常是控制項的範本部分，而不是在應用程式 UI 中宣告的專案。 (繼承來源 RoutedEventArgs)
PointerDeviceType	取得起始相關聯輸入事件的指標裝置的 PointerDeviceType 。

方法

GetPosition(UIElement)

會傳回指標位置的 x 和 Y 座標，選擇性地根據所提供 UIElement的座標原點進行評估。
