hi,

I have a generic collection implementing INotifyCollectionChanged with an Add method as the following:

    
            public void Add(TEntityType item)  
        
                    {  
        
                        if (Criteria(item))  
        
                        {  
        
                            InnerList.Add(item);  
        
                            CollectionChanged(InnerList, new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Add, item));  
        
                            if (SelectAddedItem) CurrentItem = item;  
        
                        }  
        
                    }

and it works fine with framework's ListView and DataGrid components with a binding to its ItemsSource property.

But RadGridView does not updates itself with "NotifyCollectionChangedAction.Add" but it works fine with "NotifyCollectionChangedAction.Reset". Am I doing something wrong ?
