Comentários

Uma linha de pager é exibida em um DetailsView controle quando o recurso de paginação está habilitado (definindo a AllowPaging propriedade como true). A linha do pager contém os controles que permitem que o usuário navegue até as diferentes páginas no controle. Em vez de usar a interface do usuário interna da linha de pager, você pode definir sua própria interface do usuário usando a PagerTemplate propriedade. Para especificar um modelo personalizado para a linha do pager, primeiro coloque <PagerTemplate> marcas entre as marcas de abertura e fechamento do DetailsView controle. Em seguida, você pode listar o conteúdo do modelo entre as marcas de abertura e fechamento <PagerTemplate> . Para controlar a aparência da linha do pager, use a PagerStyle propriedade.
