Kommentarer
Använd den här konstruktorn för att initiera en ny instans av DetailsView klassen. Om du vill lägga till en DetailsView kontroll dynamiskt på en sida skapar du ett nytt DetailsView objekt, anger dess egenskaper och lägger sedan till det i Control.Controls samlingen av en containerkontroll, till exempel PlaceHolder.
