Poznámky
PagerSettings Pomocí vlastnosti můžete řídit nastavení řádku pager v ovládacím DetailsView prvku. Řádek pageru se zobrazí, když je povolena funkce stránkování (nastavením AllowPaging vlastnosti na true) a obsahuje ovládací prvky, které uživateli umožňují přejít na různé záznamy v ovládacím prvku. Tato vlastnost je určena jen pro čtení; Můžete však nastavit vlastnosti objektu PagerSettings , který vrací. Vlastnosti lze nastavit deklarativní ve formuláři Property-Subproperty, kde Subproperty je vlastnost objektu PagerSettings (například PagerSetting-Mode). Vlastnosti lze také nastavit programově ve formuláři Property.Subproperty (například PagerSetting.Mode). Mezi běžná nastavení obvykle patří režim zobrazení řádku stránky a vlastní text nebo obrázky pro navigační ovládací prvky.
