Comentários

Se o InUndoRedo o parâmetro é true, você não deve alterar o XML no documento.

Exemplos

O exemplo de código a seguir demonstra os manipuladores de eventos para o AfterInsert e BeforeDelete eventos. O código exibe uma caixa de mensagem antes de um XMLNode é excluído do documento e após um XMLNode é adicionado ao documento. O exemplo também usa o RemoveChild método para excluir um nó e aumentar programaticamente a BeforeDelete evento. Este exemplo assume que o documento corrente contém uma XMLNode chamada CustomerNode que contém um nó filho chamado CustomerDateNode.

    Me.CustomerNode.RemoveChild(Me.CustomerDateNode.InnerObject)
