    Hi,

    When use Linq to sql (e.g. though LinqDataSource), and enabling filtering,
    sorting, paging, and specify what properties/columns are returned, then
    underneath, is those functions are accomplisehd by generated sql inside
    database, or LINQ still gets all columns and all rows into memory, and just
    do selecting columns, paging, filtering, sorting in memory against entities?

    Thanks a lot!
