Name
DataKeyCollection
Synopsis
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.
