// we need to do a remove and an insert - this is for updates
// otherwise its an add
// similarly, you can't do an insert at a position, its always an add !
// which makes for collection comparison a bit interesting ?
// the collection may say, do an insert at a position, but thats not possible with the current api , and instead
// we have to return to using the column span and row things instead...
// we could, just apply the view changes BUT.. we have an order problem
//Grid.SetColumn(shadowView.Item,column);
