问题描述

大家好,



我在asp.net中创建了一个自定义LogIn UserControl(ascx)

并将其放到aspx内容中Page(这是继承自Master Page)。



我想做什么:

我的UserControl上有一个ASP按钮和一个aspx页面上的链接按钮。当我单击链接按钮时,UserControl将使用Ajax Modal Pop-Up显示为POP-UP。现在的问题是,对于每个未成功的LogIn(通过检查数据库中的UserId和密码),弹出窗口消失并显示aspx页面。但它不应该。



如果每个未成功的LogIn在同一个弹出窗口中显示错误消息?

请分享代码(如果可能的话)。



提前致谢.....

Hi All,

I have created a custom LogIn UserControl(ascx) in asp.net
and placed it to aspx Content Page (this is inherited from Master Page).

What I want to do :
There is a ASP Button on my UserControl and a Link Button on aspx page. When I click on Link Button, UserControl is showing as a POP-UP using Ajax Modal Pop-Up. Now problem is that for every un-successful LogIn (by checking UserId & Password in Database), Pop-Up is disappeared & the aspx page is showing. But it should not be.

How can I display an error message in the same pop-up window for every un-successful LogIn ?
Please share the code (if possible).

Thanks in advance .....

推荐答案

是的,每次回发modalpopup都会消失。您需要从后端显示它。在您的情况下,如果登录不成功,您应该显示弹出窗口。试试这个:

Yes, for every postback modalpopup will disappear. You need to show it from back-end. In your case you should show the popup if login is not successful. Try this:
if(loginSuccessfull)
{
   //Write your code here to go to home page.
}
else
{
    //Show the modal popup extender
    ModalPopupExtender1.Show();
}
