Question

i’m looking to load a list of object with their child graph in subsonic. I know how to do it using linq to sql with dataloadoptions

i have this graph

product – location – prices

new Select().From().Where(Product.Columns.Id).IsEqualTo(productId).ExecuteSingle();

I would like for my product object to preload location and prices, so that they would not lazy load causing many query.

thanks

I use the RepositoryRecord in SubSonic which is ‘mostly’ poco. Then I make partials for those classes that load the other class when a property is selected. Besides, loading one record from the database is faster and easier than loading them all at once.

Partial Public Class Book      Private _Author as Database.Author      Property Author() as Database.Author       Get          If _Author is nothing then            ' Load the author class here.          End if          return _Author       End get       Set          '....       End Set     End Property  End Class
