The DataKeyCollection class contains a read-only
collection of primary field key names as strings. This class is used
by the BaseDataList.DataKeys property to
facillitate editing (for example, you can use a unique ID for your
key field and use it to build SQL statements when you need to update
a record in response to a user edit operation). You must specify the
data key you want to use in the
BaseDataList.DataKeyField property before you bind
the data list.
