Login control displays error message even after successful login... How come?

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :ASP.Net


I am using .net framework 2.0 witn C#. Am using the login and the CreateUserWizard and the situation is like this.

1) login.aspx page has the login control and i have a hyperlink on the same page saying 'sign up now' which when clicked redirects to the register.aspx page where i have place the createUserWizard control

2) As a new user i click on the 'sign up now' and register myself.

3) I come back to the login.aspx page and login with my new username & password.

It displays the following message 'Your login attempt was not successful. Please try again' although it is successful. How do i know this?? I placed the 'Login Name' control over the top of my page where its displaying the username with which i logged in.

i.e it displays the error msg and my user name ( which means my login was successful right?)

4) Apart from this when i logout and try to login again with the same username it displays the same error msg BUT this time it really does not login in. That username & password does not work anymore and i have to create a new one and its a cycle again from Step2.

Where am i going wrong?

How to modify the login control



I'd like to record more information than the default control allows as well as perform actions with the input when the form is submitted but I'm having trouble figuring out how.

So firstly, if I want to record the middlename for example, how would I do that, and by default, where would it go if anywhere?
When the form is submitted, I'd like to take specific input, such as just the middlename for example, and write some linq to sql code to specify when and how it's stored.
In what event would I put this code?


Customize failure text for login control


Hi all,

I would like to show the failure text in a client-side alert box for login control in c#. Please help me if there is an easy way to convert it from vb.net to c#.net. Thanks a lot!

Protected Sub Login1_LoginError(ByVal sender As Object, ByVal e As System.EventArgs) Handles Login1.LoginError
'Display the failure message in a client-side alert box
ClientScript.RegisterStartupScript(Me.GetType(), "LoginError", _
String.Format("alert('{0}');", Login1.FailureText.Replace("'", "\'")), True)

 End Sub

 Converted, but it doesn't work.

protected void Login1_LoginError(object sender, System.EventArgs e)
    //Display the failure message in a client-side alert box
    ClientScript.RegisterStartupScript(this.GetType(), "LoginError", string.Format("alert('{0}');", Login1.FailureText.Replace("'", "\\'")), true);

Login control is suddenly broken in IE7 but works perfectly on Firefox (It works on both browsers lo


Hey Guys,

 I'm new around and I thought this is probably the best place to help me solve my dilemma, I am developing a website for almost a year now and the login control was implemented a logn time ago, however all of a sudden it will not authenticate on Internet Explorer 7 when the application is published, it doesn't even provide a message that authentication was unseccssful or throws any error, it just refreshes the same page. however this problem doesn't occure when I try the same website on FireFox 2.0...Also when I run the page locally on Cassini it work great on both browsers...This is one of the weirdest errors I have ever faced. what could have gone wrong on the server side to cause this? knowing nothing changed on the server-side...I'll provide a snapshot of the login control below

<asp:Login ID="LoginControl" runat="server" BackColor="Trans

Any ideas?

Issue with Remember Me on User Login control


Hi everyone,

     I hope you can help me, I tried Google, but none of the solutions worked. Using VB.net and Membership, I have a login control in my master page with a remember me check box. When I check this box and login, some pages indicate that I am not logged in. If I go to another page, it will then indicate that I am still logged in. I have isolated one page that always indicates I am not logged in the first time I visit it, but if log in a second time and then go to it, it will finally recognize me as a user that is properly logged in. 

Some pages that this occurs on is in the top level, some pages are in a sub folder.

My MasterPage has the following Form Code:

<body bgcolor="#E0ECF9" topmargin="0" leftmargin="0">

    <form id="form1" runat="server">

My Aspx file has a troubleshooting label, several Gridviews and several DetailViews:

    <asp:Label ID="lblErRep" runat="server" Text=""></asp:Label>

My aspx.vb file has 1 line of code (Protec

Login to SQL, using Windows 7, SQL Server Error 18452, "Login failed. The login is from an untrusted

I have a File/Sharing Server which is Server 2008 SP2 and SQL Server 2008 is installed on it. My system which is on the same workgroup, was running Windows 2003 Server, which I have saved Server 2008 login credential on it and used that credential to login to SQL Server on Server 2008 system in Windows Authentication mode using SQL management studio. Recently I installed Windows 7 on that system, and I have also saved that Server 2008 credential in Windows 7 Credential Manager. The problem is here when I want to login in Windows Authentication mode using SQL management studio like past, and I will get below Error: Cannot connect to [SERVER] Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (.Net SqlClient Data Provider) Error Number: 18452 Severity: 14 State: 1 Line Number: 65536 I tried that registry solution (DisableLoopbackCheck=0x01 this thread), but no luck with that. I have checked the outgoing packets when I click on connect, and I found out that SQL management studio tried to send my local windows credential instead of Server 2008 saved credential. I don't want to login in SQL Mode, and also I don't want to convert my server to Domain controller. Is there any other solution with this issue? Regards

Login Control

Hello everybody. I am new in ASP.NET and currently working on my first web application. It is my college project. This is basically an online leave application. Which consists various label, text field etc. Now I am thinking to do this job by the following procedure. Suppose in the time of the recruitment, an organization will give a username (it may be the name of the employee) and a defined password. Now that user should logged-in to fill up his/her leave application from designed web site. When the user logged in the leave application form will be filled up by his/her name, designation etc. And there will be other things also. My team and I will submit the project along with arbitrary examples of employee. So basically what I have to do is to implement a login control with database. I want to know how I can do this job. I don't need any code. Only information/idea/any useful link will be very helpful to me. Thank you.

>>> Open a Popup window on Successful Login if something new added to website.

Hi, I would like to open a Popup window in Parallel if user Login successfully. The popup will give updates to the user that what's new added to the website. The popup will open only once if user login. If he logout and will re-login then it should not popup as we'll assume that he has been notified earlier. I have users table with user id's. It is for information that I am working in Framework 2.0 and not allowed to use any third party or AjaxToolkit. Therefore javascript or any other technique will resolve the issue. Any idea with coding example would be helpful.

custom 401/login failure error messages

I have a req to display a custom error message when a user fails to log in 3 times.  The default behavior seem to be for a redirect to something like this http://server/_layouts/AccessDenied.aspx?loginasanotheruser=true&Source=http%3A%2F%2Fserver2k7%2FPages%2FDefault%2Easpx after the third login attempt.  The resulting page just comes up as blank...I'm guessing because it failed auth.  My initial thoughts were to create a custom error page, and redirect with an http module.  That solution (while it does redirect) puts me right back to the initial problem of just a blank page being displayed after the failed auth.  I've been struggling with this for a while now, ANY thoughts or advice would be greaty appreciated.  Is it even possible?
