Kommentarer

Händelsen DateChanged inträffar när det valda datumet eller datumintervallet ändras, till exempel när användaren uttryckligen ändrar ett val under den aktuella månaden eller när markeringen implicit ändras som svar på navigeringen nästa/föregående månad. Händelsen DateSelected inträffar när användaren uttryckligen ändrar ett val. Konstruktorn DateRangeEventArgs anger start och slut för det nya datumintervall som har valts.

Mer information om hur du hanterar händelser finns i Hantera och höja händelser.
