Примеры
В следующем примере кода показано, как использовать PrintDialog элемент управления для задания AllowSomePagesсвойств , ShowHelpи Document . Чтобы запустить этот пример, вставьте следующий код в форму, содержащую PrintDialog элемент управления с именем PrintDialog1
и кнопку с именем Button1
. В этом примере требуется, чтобы событие кнопки Click и PrintPage событие docToPrint
были подключены к методам обработки событий, определенным в этом примере.
