I was surprised to know that LLBLGen EntityCollection<T> does not inherit from List<T>. I think this is one of the most important feature which we were all surpsied to know the product does not support.

What is the best way to code like this.

        DataAccessAdapter adapter = new DataAccessAdapter();
        EntityCollection<ShopEN> shopList = new EntityCollection<ShopEN>();
        adapter.FetchEntityCollection(shopList, null);

        ShopEN shop = new ShopEN(1004);
        adapter.FetchEntity(shop);

        lookupHyperLinkEdit1.DataSource = shopList;
        lookupHyperLinkEdit1.SelectedIndex = **shopList.FindIndex(delegate (ShopEN item) { return item.IdShop = shop.IdShop});

**

            DataAccessAdapter adapter = new DataAccessAdapter();
            EntityCollection<ShopEN> shopList = new EntityCollection<ShopEN>();
            adapter.FetchEntityCollection(shopList, null);

            IPredicate filter = (ShopFields.Id == 1004);
            List<int> indexes = shopList.FindMatches(filter);

            lookupHyperLinkEdit1.DataSource = shopList;
            lookupHyperLinkEdit1.SelectedIndex = indexes[0];

yes i did the same thing this morning but the bottom line of this is that llbgen EntityCollection took away the built it powerful Function Programming support of generics.

Is this something taken consideration in future versions or?...

If you trace the inheritance tree you will find the following:

EntityCollection<TEntity> : EntityCollectionBase<TEntity>
EntityCollectionBase<TEntity> : CollectionCore<TEntity>
CollectionCore<T> : IList<T>, IList

yup. i already did. it just implement IList and other generic interfaces. but that is fine, just that I am used to those function methods like Find, FindAll, FindIndex, ForEach etc. Llblgen FindMatches i think should return Entitycollection<TEntity> not List<int>. But anyway, its workable

Many thanks.
