I have a grid bound to a "Product" entity thru a LLBLDataSource set to Live Persistence.

Works great. No code. Wow.

In the system a Store has Products, a simple 1:M

Using the Fields on Related fields fields feature of the LLBL editor, I added "StoreName" to the Products entity.

On the grid I bind another column to the Product.StoreName but it's always null.

Is there a way, without code, to tell the LLBLDataSource to fetch the StoreName too? It is set to ReadOnly.

Hi Ian,

You are using Adapter, so no automatic fetchs take place for you.

You should add a prefetch path, maybe on you r Page_Load. For example:

if (!IsPostBack)
{
     IPrefetchPath2 path = new PrefetchPath((int) EntityType.ProductEntity);
     path.Add(ProductEntity.PrefetchPathStore);
     _myLLBLGenProDS.PrefetchPathToUse = path;
}

The same applies for filter (FilterToUse), sort (SorterToUse) and relations (RelationsToUse).
