Comentarios

Se muestra una fila de buscapersonas en un DetailsView control cuando la característica de paginación está habilitada (estableciendo la AllowPaging propiedad en true). La fila del buscapersonas contiene los controles que permiten al usuario navegar a las distintas páginas del control. En lugar de usar la interfaz de usuario de fila de paginación integrada (UI), puede definir su propia interfaz de usuario mediante la PagerTemplate propiedad . Para especificar una plantilla personalizada para la fila del buscapersonas, coloque primero <PagerTemplate> las etiquetas entre las etiquetas de apertura y cierre del DetailsView control. A continuación, puede enumerar el contenido de la plantilla entre las etiquetas de apertura y cierre <PagerTemplate> . Para controlar la apariencia de la fila del buscapersonas, utilice la PagerStyle propiedad .
