}

Property Value

Type: System.Web.UI.WebControls::DataKey
A DataKey that represents the primary key of the displayed record.

Remarks

When the DataKeyNames property is set, the DetailsView control automatically creates a DataKey object that represents the key field or fields for the current record. Use the DataKey property to get this DataKey object. This property is commonly used to obtain the keys and their corresponding values for the fields specified in the DataKeyNames property.

Note
As a shortcut, you can also use the SelectedValue property to determine the value of the first key field listed in the DataKeyNames property.
