Take a look here: How to: Create an ASP.NET Login Page

<asp:Login ID="Login1" 
           runat="server" 
           DestinationPageUrl="~/MembersHome.aspx">

Answer 2

If you're using Forms Authentication, just pass true as a second argument to RedirectFromLoginPage.

Otherwise, idea is essentially the same: you need to create a so-called "persistent cookie", which means that you have to specify correct cookie expiration date.

Answer 3

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                if (Request.Cookies["myCookie"] != null)
                {
                    HttpCookie cookie = Request.Cookies.Get("myCookie");
                    txtUserName.Text = cookie.Values["username"];
                    txtPassword.Attributes.Add("value", cookie.Values["password"]);



                }
            }

        }
 protected void btnLogin_Click(object sender, EventArgs e)
        {
 bool IsRemember = chkRememberMe.Checked;
                    if (IsRemember)
                    {
                        myCookie.Values.Add("username", txtUserName.Text);
                        myCookie.Values.Add("password", txtPassword.Text);
                        myCookie.Expires = DateTime.Now.AddDays(15);
                    }
                    else
                    {
                        myCookie.Values.Add("username", string.Empty);
                        myCookie.Values.Add("password", string.Empty);
                        myCookie.Expires = DateTime.Now.AddMinutes(5);
                    }
 Response.Cookies.Add(myCookie);
}
