XMLNode.ContextLeave 事件

當游標從 XMLNode 控制項 (即其中一個從屬節點) 移至原始節點的內容以外的區域時,便會發生。

命名空間:  Microsoft.Office.Tools.Word
組件:  Microsoft.Office.Tools.Word (在 Microsoft.Office.Tools.Word.dll 中)

語法

'宣告
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 SelectDeselectContextEnter 和 ContextLeave 事件的事件處理常式。當引發 SelectDeselect 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
