Comentários

Use a InsertItemTemplate propriedade para especificar o conteúdo personalizado exibido para um item no modo de inserção em um TemplateField objeto . Defina o conteúdo criando um modelo que especifica como o item no modo de inserção é renderizado.

Para especificar um modelo, primeiro lugar, abra e feche <InsertItemTemplate> marcas entre as marcas de abertura e fechamento do <TemplateField> elemento. Em seguida, adicione o conteúdo personalizado entre as marcas de abertura e fechamento <InsertItemTemplate> . O conteúdo pode ser tão simples quanto texto sem formatação ou mais complexo (inserindo outros controles no modelo, por exemplo).

Para acessar programaticamente um controle definido em um modelo, primeiro determine qual TableCell objeto no controle associado a dados contém o controle . Em seguida, use a Controls coleção do TableCell objeto para acessar o controle . Você também pode usar o FindControl método do TableCell objeto para localizar o controle, se o controle tiver uma ID propriedade especificada.

Observação

Nem todos os controles associados a dados dão suporte a esse modelo Este modelo tem suporte apenas por controles associados a dados que permitem inserir um registro, como o DetailsView controle .
