I have two value lists when first one is selected, the other one is loaded without selected element. When I try to remove selectedListItem nothing happens? It looks like list doesn’t recognize that it contains that item?

private void laodList(UltraGridRow row,  ValueListItem selectedListItem)

{           

ValueList elementList = (ValueList)row.Cells["Element"].ValueListResolved;                             

//clone list

ValueList minMaxList = elementList.Clone();

//remove selected element

minMaxList.ValueListItems.Remove(selectedListItem);

row.Cells["MinElement"].ValueList = minMaxList;

}
