The DataListCommandEventArgs class provides more information for the ItemCommand, CancelCommand, DeleteCommand, EditCommand, and UpdateCommand events of the DataList control. This information consists of an Item property identifying the affected DataListItem, and a CommandSource property that refers to the button or hyperlink that was clicked. You will have to cast this object to an appropriate type to read its properties.
