A segunda parte do exemplo de código é a página da Web. A página contém um EditorZone controle , que herda da ToolZone classe . O Button1_Click
método na página define o valor da HeaderCloseVerb propriedade.
Observe que, após o carregamento da página, você deve alternar a página para o modo de edição para ver os efeitos do código que usa a HeaderCloseVerb propriedade no EditorZone controle . Ao clicar no botão Habilitar/Desabilitar Fechar Verbo , o verbo no cabeçalho da zona deverá ser habilitado e desabilitado.
