組件：  Microsoft.Office.Tools.Word.v9.0 (在 Microsoft.Office.Tools.Word.v9.0.dll 中)

語法

Public Event ContextEnter As ContextChangeEventHandler

Dim instance As XMLNode
Dim handler As ContextChangeEventHandler

AddHandler instance.ContextEnter, handler

public event ContextChangeEventHandler ContextEnter

備註

ContextEnter 事件和 Select 事件不一樣，只有當內容變更時才會引發 ContextEnter 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。這個範例假設目前文件包含名為 CustomerNode 的 XMLNode。

Private Sub CustomerNode_Select(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs) _
    Handles CustomerNode.Select

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

Private Sub CustomerNode_Deselect(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs) _
    Handles CustomerNode.Deselect

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

Private Sub CustomerNode_ContextEnter(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs) _
    Handles CustomerNode.ContextEnter

    MsgBox("You entered the node '" & e.NewXMLNode.BaseName & "'.")
End Sub

Private Sub CustomerNode_ContextLeave(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs) _
    Handles CustomerNode.ContextLeave

    MsgBox("You left the node '" & e.OldXMLNode.BaseName & "'.")
End Sub

private void XMLNodeSelections()

    this.CustomerNode.ContextEnter +=

    this.CustomerNode.Select += 
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        CustomerNode_Select); 

    this.CustomerNode.Deselect +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(

    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    e.Selection.Borders.OutsideLineStyle =
        Word.WdLineStyle.wdLineStyleNone;
}

void CustomerNode_ContextEnter(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    MessageBox.Show("You entered the node '" +
        e.NewXMLNode.BaseName + "'.");
}

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