Exemplos

O exemplo de código a seguir demonstra evento manipuladores para o XMLNode.Select, XMLNode.Deselect, XMLNode.ContextEnter, e XMLNode.ContextLeave eventos. Quando o XMLNode.Select e XMLNode.Deselect eventos são elevados, os manipuladores de eventos de adicionar linhas duplas às bordas da seleção ou remover as linhas duplas, dependendo do evento. Quando o XMLNode.ContextEnter e XMLNode.ContextLeave evento s são aumentados, o evento manipuladores exibir mensagens que informe os nomes de nó recém-selecionado e o nó anterior ser selecionado. Este exemplo assume que o documento corrente contém uma XMLNode chamada CustomerNode.
