Namespace: Microsoft.Office.Tools.Word
Assembly: Microsoft.Office.Tools.Word.v9.0 (in Microsoft.Office.Tools.Word.v9.0.dll)
Syntax
'Declaration
Public Event BeforeDelete As NodeInsertAndDeleteEventHandler
'Usage
Dim instance As XMLNode
Dim handler As NodeInsertAndDeleteEventHandler
AddHandler instance.BeforeDelete, handler
public event NodeInsertAndDeleteEventHandler BeforeDelete
public:
event NodeInsertAndDeleteEventHandler^ BeforeDelete {
void add (NodeInsertAndDeleteEventHandler^ value);
void remove (NodeInsertAndDeleteEventHandler^ value);
}
JScript does not support events.
Remarks
If the InUndoRedo parameter is true, you should not change the XML in the document.
Examples
The following code example demonstrates event handlers for the AfterInsert and BeforeDelete events. The code displays a message box before an XMLNode is deleted from the document and after an XMLNode is added to the document. The example also uses the RemoveChild method to delete a node and programmatically raise the BeforeDelete event. This example assumes that the current document contains an XMLNode named CustomerNode that contains a child node named CustomerDateNode.
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
