    Public Sub New()
        Dim setNickNameAction As New SimpleAction(Me, "SetNickName", PredefinedCategory.Edit)
        AddHandler setNickNameAction.Execute, AddressOf SetNickNameAction_Execute
    End Sub
    Private Sub SetNickNameAction_Execute(ByVal sender As Object, ByVal e As SimpleActionExecuteEventArgs)
        Dim currentObject As Contact = TryCast(View.CurrentObject, Contact)
        If currentObject IsNot Nothing Then
            currentObject.NickName = currentObject.FirstName
        End If
    End Sub
End Class

By default, this property is set to the object that was passed in the Detail View constructor. You can change it. This will raise the View.SelectionChanged, View.CaptionChanged and View.CurrentObjectChanged events one after another.
