I'm new to subsonic and can't find a way to load data with parent or child data in a single request. Is this possible in subsonic ones?
Basically, SubSonic 2 doesn't support deep loading. However, IQueryable can be used in SubSonic 3. See the following post for details:
Subsonic Deeploads: Is It Supported?
You can do this with subsonic 2. Make a partial class with the same namespace and class name.
Then create a property that loads data when you call it.
