XMLNode.BeforeDelete 事件 (2007 系統)

更新：2007 年 11 月

當使用者從文件中刪除 XMLNode 控制項，在刪除掉該控制項之前便會發生。

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

語法

Public Event BeforeDelete As NodeInsertAndDeleteEventHandler

Dim instance As XMLNode
Dim handler As NodeInsertAndDeleteEventHandler

AddHandler instance.BeforeDelete, handler

public event NodeInsertAndDeleteEventHandler BeforeDelete

備註

如果 InUndoRedo 參數為 true，就不該變更文件中的 XML。

範例

下列程式碼範例會示範 AfterInsert 和 BeforeDelete 事件的事件處理常式。在刪除文件中的 XMLNode 之前和加入 XMLNode 至文件之後，程式碼會顯示訊息方塊。此範例也會使用 RemoveChild 方法刪除節點，並以程式設計方式引發 BeforeDelete 事件。這個範例假設目前文件包含名為 CustomerNode 的 XMLNode，這個節點又包含名為 CustomerDateNode 的子節點。

Private Sub XMLNodeInsertAndDelete()
    Me.CustomerNode.RemoveChild(Me.CustomerDateNode.InnerObject)
End Sub

Private Sub XMLNode_BeforeDelete(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs) _
    Handles CustomerDateNode.BeforeDelete

    Dim tempNode As Microsoft.Office.Tools.Word.XMLNode = _
        CType(sender, Microsoft.Office.Tools.Word.XMLNode)
    If e.InUndoRedo Then
        MsgBox(tempNode.BaseName & " element is about to be " & _
            "deleted as a result of an undo or redo operation.")
    Else
        MsgBox(tempNode.BaseName & " element is about to be " & _
            "deleted.")
    End If
End Sub

Private Sub XMLNode_AfterInsert(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs) _
    Handles CustomerDateNode.AfterInsert

    Dim tempNode As Microsoft.Office.Tools.Word.XMLNode = _
        CType(sender, Microsoft.Office.Tools.Word.XMLNode)

    If e.InUndoRedo Then
        MsgBox(tempNode.BaseName & " element was " & _
            "inserted as a result of an undo or redo operation.")
    Else
        MsgBox(tempNode.BaseName & " element was inserted.")
    End If
End Sub

private void XMLNodeInsertAndDelete()
{
    this.CustomerDateNode.AfterInsert +=
        new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
        XMLNode_AfterInsert);

    this.CustomerDateNode.BeforeDelete +=
        new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
        XMLNode_BeforeDelete);

    this.CustomerNode.RemoveChild(this.CustomerDateNode.InnerObject);
}

void XMLNode_BeforeDelete(object sender, 
    Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
    Microsoft.Office.Tools.Word.XMLNode tempNode =
        (Microsoft.Office.Tools.Word.XMLNode)sender;

    if (e.InUndoRedo)
    {
        MessageBox.Show(tempNode.BaseName + " element is about to be " +
            "deleted as a result of an undo or redo operation.");
    }
    else
    {
        MessageBox.Show(tempNode.BaseName + " element is about to be " +
            "deleted.");
    }
}


void XMLNode_AfterInsert(object sender,
    Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
    Microsoft.Office.Tools.Word.XMLNode tempNode =
        (Microsoft.Office.Tools.Word.XMLNode)sender;

    if (e.InUndoRedo)
    {
        MessageBox.Show(tempNode.BaseName + " element was " +
            "inserted as a result of an undo or redo operation.");
    }
    else
    {
        MessageBox.Show(tempNode.BaseName + " element was inserted.");
    }
}
