Здесь библиотека сделана на основе примера из RSDN, только у меня одно поле типа MaskEdit и маска у него должна быть "00:00:00".
Experimenter, может быть посмотришь код? Где то я делаю что-то не так... Когда в проекте использую колонку типа DataGridViewPassportColumn (я её не переименовала), значение у меня не устанавливается |
