Accessing the Items property of a List control or the Items property of a SelectionList control retrieves a MobileListItemCollection object. You can add or remove items from the collection at run time.
A MobileListItemCollection object inherits from the ICollection interface.
The following code example shows how you manipulate items in the MobileListItem object through the MobileListItemCollection class. The code uses the selected item's index into the SelectionList.Items property.
