i watched How Do I: Build a WPF Data Entry Form Using Entity Framework?
very confused around 15:30. when the presenter said something like
when you create a LINQ query, we wont get a rich collection ...
whats does she mean my "rich".
the start code looks like... whats wrong with that. even if i change db.Customers.Execute(...) with a LINQ query, the code still works. why the need for a new observable collection and why ListCollectionView instead of BindingListCollection view. whats the diff between the 2
// customerSource is a CollectionViewSource stored in Window.Resources
// db is of type OMSEntities (which is the Entity Collection Name, what does this mean?)
customerSource.Source = db.Customers.Execute(...);
this.view = (BindingListCollectionView) customerSource.View;
the code after looks like (~21:38)
results = from cust in db.Customers ...
customerData = new CustomerCollection(results, db);
customerSource.Source = customerData
view = (ListCollectionView) customerSource.View;
