Hi,

How are you assigning this value from your login page?

i read the text, so is Context.User.Identity.Name automatically directed by the os thru the browser?

it's just that i am trying to authenticate using database, so I am not quite sure who assigns Context.User.Identity.Name a value?

i think the example posted was authenticating via file since small # of allowed users.

Hi,

When your users login and you authenticate them by checking that their username and password matches, you can then call

FormsAuthentication.RedirectFromLoginPage(txtUsername, ChkPersist.Checked)

Where txtUsername is the id of your text box that accepts the username.

ChkPersist is the id of a checkbox if you want to set a persistant cookie (if not use "false")

Now you can retrieve the username by using

Label1.Text = HttpContext.Current.User.Identity.Name

Your web config file must also have

<authentication mode="Forms">
<forms name=".ASPXAuth" loginUrl="Login.aspx" protection="All" timeout="60" />
</authentication>

(change the LoginUrl to your own)
