Страница не обновляется при нажатии кнопки

Question

В моем проекте есть количество страниц, наследующих одну и ту же главную страницу, и все отвечают за исключением 1 или 2 страницы, никаких изменений в коде не происходит. Я вставил точку останова на кнопку кнопки без эффекта. Как я могу проверить проблему. Пожалуйста, помогите

Вот код моей страницы

Мой клиент сторона код кнопки

protected void btnInsert_Click(object sender, EventArgs e) 
    { 
     try 
     { 
     int productID, quantity; 
     string stockType; 
     DateTime stockDate; 

     productID = int.Parse(ddlprdctname.SelectedValue); 
     quantity = int.Parse(txtquantity.Text.Trim()); 
     stockType = ddlstocktype.SelectedValue.ToString().Trim(); 
     stockDate = DateTime.Parse(txtstockdate.Text.Trim()); 
     ProductStock prdctstock = new ProductStock(); 
     prdctstock.ProductID = productID; 
     prdctstock.Quantity = quantity; 
     prdctstock.StockType = stockType; 
     prdctstock.StockDate = stockDate; 
     if (new InsertAction().InsertData(prdctstock))

Answer 1

Поместите контрольную точку где-то, где она попадает. Посмотрите на стек вызовов и перейдите к точке, когда вы обнаружите, почему она не идет к методу, который вы хотите вызвать. Невозможно многое сделать без дополнительной информации. Надеюсь, что это помогает

Answer 2

Я видел несколько нежелательных Кодекса

1), пожалуйста, удалите ValidationGroup="vg1" в ваших всех элементов управления ASP.NET, за исключением кнопки.

2) Не используйте панель, некоторое время кнопки мыши не работает на использование панели управления, поэтому, пожалуйста, используйте таблицу вместо панели (или удалить жерех:. Контроль панели)

3) и проверить, событие нажатия кнопки так же, как и на стороне сервера.

4) Если вы дадите мне наш код на стороне сервера, тогда я отвечу вам!
