    I bind radGridView to QueryableCollectionView property. When i add new item to this collection radGridView does not get updated data.
    CurrentCollection.AddNewItem(new Model{id = 0, name = "empty"});
    But, on http://www.telerik.com/help/silverlight/t_telerik_windows_data_queryablecollectionview.html said that it's implement IQueryableCollectionView.

    With best regards, Alex.

    Does your source collection support adding items? It has to be an IList which is not with a fixed size.  Otherwise, adding items would be impossible.
