asp.net(C#Web窗体按钮)clickinn和刷新页面 [英] asp.net (c# web form button) clickinn and refreshing page

问题描述

hi
我在asp.net(框架4)中有一个登录页面，我使用c#即时消息，好了，当我输入用户名和密码时，然后单击登录按钮(而不是其Web表单按钮的html按钮)，它会执行类代码(检查数据库)，但是，我必须再次单击它以使我转至CMS的主页.和ia在我所有的按钮中都存在相同的问题，即使我单击添加按钮进行上传，它也会刷新页面，甚至注销时，我也必须单击两次！当会话刷新页面时，我所有的变量(int字符串...)都丢失了，我使用了1分钟超时的会话.这对我来说是个大问题，所以我应该怎么做才能避免通过单击按钮来刷新页面！登录页面的事件处理程序，您可以:

 如果(IsPostBack)
{
    验证指定的用户凭据
}
如果(用户有效有效)
{
    Response.Redirect(" );
} 

您是否在调试器下运行页面以查看发生了什么?

解决方案

In your Page_Load event handler of your login page, you can :

if (IsPostBack)
{
    verify specified user credentials
}
if (user is valid)
{
    Response.Redirect("loggedin.aspx");
}

Have you run your page under the debugger to see what''s happening?
