我是学ASPNET的新手,我写了个简单的登录程序,不知是myButton的Click事件触发不了,还是数据库连不上,在登录无论输入什么,反应都是一样的(点登录后,没有反应).这个问题我找了好几天都没找出来,谁能帮帮我?非常感谢!!
下面是我写的程序:

{
this.Load += new System.EventHandler(this.Page_Load); } 里面加一句
this.myButton.Click +=new System.EventHandler(this.myButton_Click);
或且删了myButton,重新生成一个,生成后,应该会自动生成上面的那句。
private void InitializeComponent()
{
this.Button1.Click += new System.EventHandler(this.Button1_Click);//加上这一句 this.Load += new System.EventHandler(this.Page_Load); }
