XMLNodes.ContextLeave 事件

当光标从 XMLNodes 集合的节点或子代节点之一移到原始节点上下文以外的区域时发生。

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 ContextLeave As ContextChangeEventHandler

event ContextChangeEventHandler ContextLeave

备注

ContextLeave 事件与 Deselect 事件不同。ContextLeave 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。有关更多信息，请参见XMLNodes 控件。

示例

下面的代码示例演示 Select、Deselect、ContextEnter 和 ContextLeave 事件的事件处理程序。引发 Select 和 Deselect 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)


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

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


    MessageBox.Show("You entered the node '" & _
        e.NewXMLNode.BaseName + "'.")
End Sub

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


    MessageBox.Show("You left the node '" & _
        e.OldXMLNode.BaseName + "'.")

    e.Selection.Borders.OutsideLineStyle =

}

void SampleInsertNodes_ContextEnter(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    MessageBox.Show("You entered the node '" +

}

void SampleInsertNodes_ContextLeave(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    MessageBox.Show("You left the node '" +
        e.OldXMLNode.BaseName + "'.");
