I've created a page to add users, using the CreateUserWizard, I use the Login Control to login.
I have setup the config file to use my SQL server, not express
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=xxxx.xxxx.xxxx.xxxx;Initial Catalog=aspnetdb;Persist Security Info=True;User ID=xxxx;Password=xxxxxx" providerName="System.Data.SqlClient" />
I go to the create user page, add a user.
I can SEE the user on the database using Server Management Studio...
I go to signon and get "Your login attempt was not successful. Please try again."
I have not customized the login control in any way. (OR the createuserwizard)
HOW can I tell where the Login tool is going to get userid and password info?
How can I tell if it is not finding the user or the password does not match?
I would like to use validation to check the length of a textbox entry (character length) when the textbox loses focus. how I can do this?

I want check userid availability on registration from like timesjobs com,(a small progess image till query processing)
i have one registration form in which userid and password field filled by user.
i want to check the userid availability which is entered by user .
I'm wonder how i can get the userid just after i validate. Is there another method i can use to login than
FormsAuthentication.RedirectFromLoginPage(userName, true);
Here's what i have.
if (Membership.ValidateUser(userName, password))
{
// i get a null object on the below as i haven't logged in yet
Guid UserID = new Guid(Membership.GetUser(User.Identity.Name).ProviderUserKey.ToString());
// some other logic that requires UserId
}
How can we check whether the USERID exists in Active Directory or not.

View 5 RepliesWe have a system where an administrator can login and create other users. If the administrator creates another user, then logs out and immediately logs back in with the new user information the UserID Guid is not available. If you log out and login again with the new username it works, or if you simply refresh the page it works.
Why does it not work on the first run?

I've got a text box on my page called txtNotes - multiline textbox.
When I add the text into the sql server database, the line feeds are not getting entered.
I have a function that replaces the line feeds with "<br>" and it's still all in one line. Also I don't see the normal square type entity after each line in the database, that is normally there for a line feed.
However, when I copy from the database and paste it to Notepad, it is formatted correctly

View 8 RepliesI am learning how to use repeater and datagrid. I've been able to update a datagrid successfully. I have two text box, which take an item description and quantity, save them in a database, and display them back in a datagrid whenever the user access the page again. If the user were to enter a value, let say description ='coffee' and quantity= '15', it would save them in the database properly. However, if the user refreshed the page, a second row with the same value ('coffee', '15') is added to the database again. How can I avoid this from happening?
