I followed every step. I have the database, I modified the Web.config to use this provider, with the correct connection string, and the authentication mode is set to Forms. Created some users to test with. I created a Login.aspx and put the Login control on it. Everything works fine until the point that a user can http://stackoverflow.com/questions/62013/problem-with-login-control-of-asp-net log in. I call Default.aspx, it gets redirected to Login.aspx, I enter the user and the correct password. No error message, nothing seems to be wrong, but I see again the Login form, to enter the user's login information. However if I check the cookies in the browser, I can see that the cookie with the specified name exists. I already tried to handle the events by myself and check, what is happening in them, but no success. I'm using VS2008, Website in filesystem, SQL Express 2005 to store aspnetdb, no role management, tested with K-Meleon, IE7.0 and Chrome. Any ideas?

Note: I have not tested this since I have not installed the database etc.. However, I am pretty sure this is the issue. You need to set the MembershipProvider Property for your ASP.NET controls.

I can set a custom failure text and I can add a literal on the page where the failure text is displayed if the login fails. I also have a validation summary on the page in which I collect all errors that can occur (for the moment it just validates that the user has entered a login name and a password. It would be really nice if I could add asp.net login control the failure text of the login control as an item in the validation summary, but I'm not sure if this is even possible? Hoping that the massive brainpower of stackoverflow can give me some pointers? Thanks! /Thomas Kahn PS. I'm coding in C#. c# asp.net login-control validationsummary share|improve this question asked Apr 8 '10 at 8:54 tkahn 99721434 Are you using the Login control as it is, or have you defined a custom LayoutTemplate for it? Is there actually anything more than the login form that you're attempting to validate here? I ask mainly because "informative" error messages (such as "Your password was incorrect") are often considered a security hole - you've given a potential hacker one important piece of information - they have a valid username, so only need to change the password, where as a generic message (say "Invalid details supplied") means they may need to try both. –Zhaph - Ben Duguid Apr 8 '10 at 9:31 Hi! Thanks for replying! Yes, I'm using a LayoutTemplate. All I require from the user is a username and a password - nothing else. The current validation is just to check for empty form fields. If the login fails, I just want to add an item to the validation summary that tells the user that the login failed. –tkahn Apr 9 '
In this tutorial we will demonstrate how to customize ASP.NET’s Login Control to display detailed errors for our users. Adding the Login Control At this point in the tutorial I have created a new ASP.NET Empty Web Site in Microsoft Visual Web Developer and have added in a blank Web Form named Default.aspx. To add the login control, open up the Default.aspx page in Design mode and: Expand the Login tab in your toolbox. Drag and drop a Login Control onto the Web Form. Adding Error Messages At this point, we want to add some specific error messages to this control in the event that a login attempt fails. To do this: Right click the Login Control and select Properties. In the Properties window click the Events icon. Double click the LoginError event to begin editing that method. We used over 10 web hosting companies before we found Server Intellect. Their dedicated servers and add-ons were setup swiftly, in less than 24 hours. We were able to confirm our order over the phone. They respond to our inquiries within an hour. Server Intellect's customer support and assistance are the best we've ever experienced. This method will run every time our Login Control fails to log in successfully. Here we need to determine what is causing the error. First, at the top of the class add in the following using statement: C# using System.Web.Security; 012 using System.Web.Security; This will allow us to use the Membership class which we will need to get data from our user that is attempting to login. Next, we need to add in the code to display the error messages. Add the following code to the LoginError event method: C# MembershipUser currentUser = Membership.GetUser(Login1.UserName); if (currentUser == null) { //The GetUser method could not find a user with the given name. //This indicates that the username entered does not exist. Login1.FailureText = "Invalid Username. Please try again."; } else { //Check to see if the error occurred because they are not approved. if (!currentUser.IsApproved) Login1.FailureText = "Your account has not yet been approved by an administrator."; //Check to see if they are currently locked out. else if (currentUser.IsLockedOut) Login1.FailureText = "You have been locked out, please try again in 10 minutes."; //If none of these conditions have been met, the password is incorrect. else Login1.FailureText = "Invalid Password. Please try again."; } 0123456789101112131415161718192021 Membershi
