Я получаю исключение с пустой ссылкой на singleKingButton.Checked = true; в событии загрузки страницы. Если я прокомментирую это, я все равно получаю один на следующей строке, задавая дату. Странно, что страница загружается отлично, когда я нажимаю кнопку отправки, чтобы получить ошибку. Заранее спасибо!null Исключение ссылки на странице переадресация

Являются ли эти элементы управления объявленными на вашей странице? Вы удаляете их каким-либо образом? – mason
Да и нет. (Я предполагаю, что вы ссылаетесь на текущую страницу, а не на страницу, на которую она перенаправляется, когда нажата кнопка) Я также добавил html-код. благодаря! –
