Uwagi
PreviousViewCommandName Użyj pola, aby reprezentować nazwę polecenia "PrevView".
Możesz użyć wartości tego pola, aby skorzystać z MultiView automatycznego aktualizowania kontrolki aktywnej View kontrolki. Jeśli na przykład kontrolka View zawiera kontrolkę Button , która przechodzi do następnego Viewelementu , możesz ustawić CommandName właściwość na wartość PreviousViewCommandName pola, czyli "PrevView". MultiView Powoduje to automatyczne zwiększanie wartości ActiveViewIndex właściwości przez kontrolkę po kliknięciu przycisku.
