The InitializeItem method is used primarily by control developers to extend the DataList control.
The CreateControlHierarchy method uses the CreateItem and InitializeItem methods to create DataListItem controls that represent the header, footer, separator, and data-bound items contained in the data list. You can access the data-bound items for the data list through the Items collection. You can access all item types, including the header, footer, and separator items, through the Controls collection.
