XMLNodes.ContextEnter 事件

当光标从节点上下文以外的区域移入 XMLNodes 集合的节点或子代节点之一时发生。

命名空间:  Microsoft.Office.Tools.Word
程序集:  Microsoft.Office.Tools.Word(在 Microsoft.Office.Tools.Word.dll 中)

语法

声明
Event ContextEnter As ContextChangeEventHandler
event ContextChangeEventHandler ContextEnter

备注

ContextEnter 事件与 Select 事件不同。 ContextEnter 事件仅在上下文更改时引发,并可为嵌套在同一层级的多个 XMLNodes 控件引发。 有关详细信息,请参阅 XMLNodes 控件

示例

下面的代码示例演示 SelectDeselect、ContextEnter 和 ContextLeave 事件的事件处理程序。 引发 SelectDeselect 事件时,事件处理程序会根据具体事件为所选内容的边框添加双线或移除双线。 引发 ContextEnter 和 ContextLeave 事件时,事件处理程序会显示消息,指出最新选择的节点和之前选择的节点的名称。 此示例假定当前文档包含一个名为 SampleInsertNodes 的 XMLNodes 集合。

Private Sub SampleInsertNodes_Select(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)


    e.Selection.Borders.OutsideLineStyle = _
        Word.WdLineStyle.wdLineStyleDouble
End Sub

Private Sub SampleInsertNodes_Deselect(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)

End Sub

Private Sub SampleInsertNodes_ContextLeave(ByVal sender As Object, _
