Event ContextLeave As ContextChangeEventHandler
event ContextChangeEventHandler ContextLeave
備註
ContextLeave 事件和 Deselect 事件不一樣,只有當內容變更時才會引發 ContextLeave 事件。如需詳細資訊,請參閱XMLNode 控制項。
範例
下列程式碼範例會示範 Select、Deselect、ContextEnter 和 ContextLeave 事件的事件處理常式。當引發 Select 和 Deselect 事件時,事件處理常式會為選取範圍的邊框加上雙線,或是移除雙線 (視事件而定)。當引發 ContextEnter 和 ContextLeave 事件時,事件處理常式會顯示訊息,說明最新選取的節點以及上一個所選節點的名稱。此範例假設目前的文件包含名為 CustomerNode 的 XMLNode。
