Thread: Login functionality of the shop?

hello, i have created a custom login control with two Textboxes, now i want to login an user, which function must i use?

refer to the Login_Click event on signin.aspx for the login logic.

Thx at first.

I have put these Controls on my template.ascx, with a cross page postback i refer to the signin.aspx Now i have following problem, when authenticate the first time, i get logged in. After that a have logged out and repeated this procedure, then comes the postback but i´m not logged in.
This function only every second time, where is the problem?


In the signin.aspx i have put these code to request the user data of the previous page:

Code:

if (PreviousPage != null)
            {
                EMail.Text = ((TextBox) PreviousPage.FindControl("tbEmail")).Text;
                txtPassword.Text = ((TextBox) PreviousPage.FindControl("tbPassword")).Text;

                LoginButton_Click(null, null);
            }

In the debugger i can see that the user is logged in, but in the shop nothing happens. Is there something with cookies or the cross page postback ?
