Use a FooterRow propriedade para acessar programaticamente o GridViewRow objeto que representa a linha de rodapé em um GridView controle .
Observação
A FooterRow propriedade está disponível somente depois que o GridView controle cria a linha de rodapé no RowCreated 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 depois que o GridView controle tiver sido renderizado; caso contrário, o GridView controle substituirá todas as alterações.
