Comentários

A linha do rodapé é exibida na parte inferior do DetailsView controle quando a FooterText propriedade ou FooterTemplate é definida. Use a FooterRow propriedade para acessar programaticamente o DetailsViewRow objeto que representa a linha do rodapé.

Observação

A FooterRow propriedade só está disponível depois que o DetailsView controle cria a linha de rodapé no ItemCreated evento.

Essa propriedade é comumente usada quando você precisa manipular programaticamente a linha do rodapé, por exemplo, ao adicionar conteúdo personalizado. Qualquer modificação na FooterRow propriedade deve ser executada após a renderização do DetailsView controle; caso contrário, o DetailsView controle substituirá quaisquer alterações.

Para controlar o estilo da linha do rodapé, use a FooterStyle propriedade .
