Poznámky

MergeWith Pomocí metody zkombinujte vlastnosti stylu zadaného Style objektu s touto instancí DataGridPagerStyle třídy. Pokud je vlastnost z této instance již nastavena na hodnotu, vlastnost se nezmění. Pokud vlastnost není nastavena, tato metoda nastaví tuto vlastnost s hodnotou z odpovídající vlastnosti objektu Style .
