Comentarios
El control de origen de datos SqlDataSource representa los datos de una base de datos relacional basada en SQL como controles enlazados a datos. El control SqlDataSource se puede utilizar junto con el control enlazado a datos para recuperar datos de una base de datos relacional y mostrar, editar y ordenar los datos de una página Web con muy poco o nada de código.
Para obtener más información sobre cómo usar el control SqlDataSource, vea Información general sobre SqlDataSource (Control de servidor Web).
Ejemplo
En el ejemplo de código siguiente se muestra cómo utilizar un control SqlDataSource mediante declaración para recuperar datos de Microsoft SQL Server y mostrarlos en un control GridView.
