Property Value

Type: System::Object
The value of the key field at index 0 in the DataKey.

Instead of using the Item or the Values property to retrieve a key field value from a DataKey object, you can use the Value property as a shortcut to determine the value of the key field at index 0 in the DataKey object. This property is commonly used to determine the key field value of a record when the record has only one key field.

NoteNote:

If the DataKey object does not contain any key fields, nullptr is returned.

The following code example demonstrates how to use the Value property to determine the primary key value of a record.

No code example is currently available or this language may not be supported.
