Su código de muestra que utilizar el enlace con DataBind () llamadas. De esta manera, usted debe cambiar manualmente el índice de página de enganche PageIndexChanged, fuente de datos de asignación a la red y se unen ella. Como alternativa, utilice NeedDataSource unión a algún repuesto manual de codificación.
