PropertyGrid for Silverlight

Following my question, Is there a (preferably free) Prop开发者_Go百科ertyGrid for silverlight out there which supports editing ICollections?

Thanks.

There is a newest version of the same control and according to the documentation it is supporting Collections. You could find it in Silverlight 5 Property Grid
