I’m working with silverlight and I want to filer an ObservableCollection.
So I started to look att ICollectionView, because there is no CollectionViewSource in Silverlight and it contains an absure amount of methods and events. I’ve searched for a while and I wonder if anyone has example code of an implementation of ICollectionView?
Unfortunately ICollectionView is only used for the DataGrid in Silverlight 2.0, and its only implementation is ListCollectionView, which is internal to System.Windows.Controls.Data.
If you are not binding to a DataGrid, ICollectionView will not give you much because it is not used by the basic controls (such as listbox) as far as I can tell, since it is defined in the Data controls assembly and not in the core.
This is a pretty big difference with WPF.
But to the point of your question, the assembly containing the DataGrid does have an implementation that might help you if you want to learn how it is done. Worst case, reflector is your friend…
