Как я могу скрыть выходные при использовании Календарного управления ASP.NET?

Поскольку управление обеспечивается, нет никакого способа сделать это, не переопределяя управление. Один способ сделать это к, должен переопределить OnDayRender и Методы рендеринга для удаления информации из вывода до передачи обратно его клиенту.

Следующее является снимком экрана того, на что похоже управление при рендеринге:

Следующее является основным переопределением управления, которое демонстрирует удаление дневных столбцов выходных дней от управления.
