问题描述
嗨专家，
我在六个月之前部署了一个网站。
它工作正常，直到约会。
这个，登录页面第一次完全加载。
它包含父子组合框控件。
因此，当我从第一个组合框中选择一个值时，它将填充第二个组合框。
然后我就可以在此站点登录。
但现在，我的第一个组合成功填写，但是当我从中选择一个选项时，页面无法回发而不加载第二个组合框。
即使我无法点击登录按钮。
如何可行以及如何解决这个问题。
任何地方都会很感激。
提前感谢
这是我的代码
Login.aspx
Hi Experts,
I have deployed one site before six month.
It is working fine till the date.
in this, the login page load completely at first time.
and it contain parent-child combo box controll.
So when i select one value from first combo box, it will fill second combo box.
then i can able to login in this site.
but now, my first combo filled successfully, but when i select one option from it, page can not post back and not load second combo box.
even i am not able to click login button.
How it is possible and how can i resolve this problem.
any hell will be appreciate.
thanks in advance
This is my Code
