You wire up the event handlers to an instance of Collection< XLinkRow > then replace it with another one. Needs a redesign really but you can use this instead:

public Collection<XLinkRow> Rows
>>        {
>>            get { return _Rows; }
>>            set 
>>            {

>>                foreach (XLinkRow x in value)
>>                    Rows.Add(x);
>>            }
>>        }

Well - that's the problem but I don't think my solution works properly - looks like the list now doesn't show up in the Form...
Knocking off time I'm afraid - hope you have enough info to work out a proper solution.....
