Comentários

Use a Row propriedade para acessar programaticamente o FormViewRow objeto que representa a linha de dados. A linha de dados contém conteúdo diferente com base no modelo renderizado para o modo atual (especificado pela CurrentMode propriedade). Você só pode acessar o conteúdo do modelo para o modo atual. A tabela a seguir mostra qual modelo é usado para cada modo.

Modo Modelo renderizado
Editar EditItemTemplate
Inserir InsertItemTemplate
Somente leitura ItemTemplate

Observação

A Row propriedade só está disponível depois que o FormView controle cria a linha de dados no ItemCreated evento.

Essa propriedade é comumente usada quando você precisa manipular programaticamente a linha de dados, por exemplo, ao adicionar conteúdo personalizado. Qualquer modificação na Row propriedade deve ser executada depois que o FormView controle tiver sido associado a dados; caso contrário, o FormView controle substituirá quaisquer alterações.
