XMLNodes.BeforeDelete 事件 (2007 系統)
更新：2007 年 11 月
當使用者在刪除控制項之前，先從集合中刪除 Microsoft.Office.Interop.Word.XMLNode 或從屬節點便會發生。
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 XMLNodes
Dim handler As NodeInsertAndDeleteEventHandler
AddHandler instance.BeforeDelete, handler
public event NodeInsertAndDeleteEventHandler BeforeDelete
備註
如果 InUndoRedo 參數是 true，就不應該變更文件中的 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。在從文件中刪除 Microsoft.Office.Interop.Word.XMLNode 之前，以及將 Microsoft.Office.Interop.Word.XMLNode 加入至文件之後，程式碼會顯示訊息方塊。範例也使用 Add 方法，在指定的範圍上將新項目加入 XMLNodes 集合，並且用程式設計的方式引發 AfterInsert 事件。這個範例假設目前文件包含名為 SampleInsertNodes 的 XMLNodes 集合，這個集合有名為 SampleNode 的父 XMLNode。
Private Sub XMLNodeAddAndDelete()
Dim range1 As Object = Me.SampleInsertNodes(1).Range
' This will raise the AfterInsert event.
Dim node1 As Word.XMLNode = _
Me.SampleInsertNodes.Add("MemoFrom", _
Me.SampleNode.NamespaceURI, range1)
End Sub
Private Sub SampleInsertNodes_AfterInsert(ByVal sender As Object, _
ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs) _
Handles SampleInsertNodes.AfterInsert
If e.InUndoRedo Then
MessageBox.Show("A child element of SampleInsertNodes was " & _
"inserted as a result of an undo or redo operation.")
Else
MessageBox.Show("A child element of SampleInsertNodes " & _
"was inserted.")
End If
End Sub
Private Sub SampleInsertNodes_BeforeDelete(ByVal sender As Object, _
ByVal e As Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs) _
Handles SampleInsertNodes.BeforeDelete
If e.InUndoRedo Then
MessageBox.Show("A child element of SampleInsertNodes " & _
"is about to be deleted as a result of an undo or " & _
"redo operation.")
Else
MessageBox.Show("A child element of SampleInsertNodes " & _
"is about to be deleted.")
End If
End Sub
private void XMLNodeAddAndDelete()
{
object range1 = this.SampleInsertNodes[1].Range;
this.SampleInsertNodes.AfterInsert +=
new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
SampleInsertNodes_AfterInsert);
this.SampleInsertNodes.BeforeDelete +=
new Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventHandler(
SampleInsertNodes_BeforeDelete);
// This will raise the AfterInsert event.
Word.XMLNode node1 = this.SampleInsertNodes.Add("MemoFrom",
this.SampleNode.NamespaceURI, ref range1);
}
void SampleInsertNodes_AfterInsert(object sender,
Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
if (e.InUndoRedo)
{
MessageBox.Show("A child element of SampleInsertNodes was " +
"inserted as a result of an undo or redo operation.");
}
else
{
MessageBox.Show("A child element of SampleInsertNodes " +
"was inserted.");
}
}
void SampleInsertNodes_BeforeDelete(object sender,
Microsoft.Office.Tools.Word.NodeInsertAndDeleteEventArgs e)
{
if (e.InUndoRedo)
{
MessageBox.Show("A child element of SampleInsertNodes " +
"is about to be deleted as a result of an undo or " +
"redo operation.");
}
else
{
MessageBox.Show("A child element of SampleInsertNodes " +
"is about to be deleted.");
}
}
