Příklady
Tento příklad ukazuje, jak pomocí objektu Style změnit vlastnosti stylu více ovládacích prvků najednou. Pokaždé, když se Style změní jedna z hodnot vlastností, musí každý ovládací prvek volat svou ApplyStyle metodu. Všimněte si, že ne všechny ovládací prvky podporují všechny uvedené vlastnosti. Pokud ovládací prvek nepodporuje konkrétní vlastnost, vzhled ovládacího prvku se při změně hodnoty vlastnosti nezmění.
Poznámka
Následující ukázka kódu používá model s jedním souborem kódu a nemusí správně fungovat, pokud je zkopírován přímo do souboru s kódem na pozadí. Tento vzorový kód musí být zkopírován do prázdného textového souboru s příponou .aspx. Další informace o modelu kódu webových formulářů najdete v tématu ASP.NET model kódu stránky webových formulářů.
