參數

備註

在建立 ContextChangeEventHandler 委派 (Delegate) 時,您要識別處理事件的方法。 若要使事件與您的事件處理常式產生關聯,請將委派的執行個體 (Instance) 加入至事件。 在您移除該委派之前,每當事件發生,就會呼叫事件處理常式。 如需委派的詳細資訊,請參閱事件和委派

範例

下列程式碼範例會示範 XMLNode.SelectXMLNode.DeselectXMLNode.ContextEnterXMLNode.ContextLeave 事件的事件處理常式。 當引發 XMLNode.SelectXMLNode.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 XMLNode.ContextEnterXMLNode.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
