Comentários
The MultiView controle é um contêiner para um agrupar de View controles. Ele permite que você defina um agrupar de View controles, onde cada View controle contém controles filhos. Seu aplicativo pode depois processar um determinado View controle para o cliente com base em critérios, sistema autônomo identidade do usuário, sistema autônomo preferências do usuário e informações que passam por um parâmetro de seqüência de caracteres de consulta. Você também pode usar o MultiView controle para criar assistentes. Nesse cenário, cada View controle que está contido em um MultiView controle representa uma etapa diferente ou uma página do assistente. Você também deve usar esse controle para desenvolver aplicativos de tela múltiplo para dispositivos móveis. Esse controle oferece a mesma funcionalidade sistema autônomo o ASP.NET móvel Form controlar no Microsoft .NET estrutura versão 1.1.
Para obter mais informações sobre como usar o MultiView e View controles, consulte Visão Geral dos Controles do Servidor Web View e MultiView.
Exemplo
O exemplo de código a seguir demonstra como usar um MultiView controle para criar uma pesquisa básica. Cada View o controle é uma pergunta de pesquisa separado. Quando o usuário clica o Anterior botão em qualquer página, a ActiveViewIndex propriedade será reduzida para navegar até anterior View controle. Quando o usuário clica o Próximo botão em qualquer página, a ActiveViewIndex propriedade é incrementada para navegar até o próximo View controle.
