Question

<authentication mode="Forms">
        <forms loginUrl="LoginPage.aspx"
           protection="All"
           timeout="1"
           name=".ASPXAUTH"
           path="/"
           requireSSL="false"
           slidingExpiration="false"
           defaultUrl="HomePage.aspx"
           cookieless="UseDeviceProfile"
           enableCrossAppRedirects="false"/>
      </authentication>

protected void btnSubmit_Click(object sender, EventArgs e)
        {
           int recordExistCount = fc.Authenticate(txtUsername.Text.Trim(), txtPassword.Text.Trim());
           if (recordExistCount == 1)
           {
               Session["User"] = "Authenticated";
               Session["Username"] = txtUsername.Text.Trim();
               fc.IsOnlineRecord(Session["Username"].ToString(),true);
               FormsAuthentication.RedirectFromLoginPage(Session["Username"].ToString(), true);
           Response.Redirect("HomePage.aspx");
           }
           else
           {
               lblStatus.Text = "Username or password specified are incorrect";
               lblStatus.BackColor = Color.Yellow;               
           }
        }

Forms authentication doesnt work properly. After one successfull login , I go to the website url and it doesnt go to Homepage and instead takes me again to the loginpage.
What am I doing wrong?

It seems as though you are not setting the Formsauthentication. Therefore, in the code behind of the LoginPage.aspx – on the login click event try something like this

protected void btnLogin_Click(object sender, EventArgs e)
        {
            try
            {
                //get the user details and authenticate them against whatever means you need to
                FormsAuthentication.RedirectFromLoginPage(authenticatedUser.Email, false);
                Response.Redirect("~/HomePage.aspx");
            }
            catch
            {
                //catch any errors here
            }
        }
