This article shows you how to implement the above functionality in ASP.NET.
Step 1: Add a checkbox in the login page
You can add a checkbox in the login page by dragging and dropping a checkbox from the toolbox when you are in page design mode, or you can create a checkbox programmatically in the code behind class.
The following code shows you how to do this in the second way:
private CheckBox _rememberMeCheckBox;
//.....
this._rememberMeCheckBox = new CheckBox();
this._rememberMeCheckBox.Text = "Remember me next time");
this._rememberMeCheckBox.Checked = true;
this.Controls.Add(this._rememberMeCheckBox);
//.....
Setp 2: Creat a cookie when a subscriber login
create a cookie in the Cliked event handler of the login button:
private void _LoginButton_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
//....
//....
ApplicationUser user = ApplicationUser.RetrieveCurrentUserByLoginId(userId);
if (user != null && user.Password == password)
{
Session["user"] = user;
Response.Cookies.Remove("CookieFromXXX");
if (this._rememberMeCheckBox != null &&
this._rememberMeCheckBox.Checked)
{
HttpCookie cookie = new HttpCookie(string.Format("cookie_from_{0}", this._host));
cookie.Values.Add("userId", user.Id);
cookie.Values.Add("pwd", user.Password);
cookie.Expires = DateTime.Now.AddYears(1);
Response.Cookies.Add(cookie);
}
}
//....
//....
}
Step 3: Override the OnInit method in the base page
If there is a base page which is the parent page of all other pages in your website, you can override the the OnInit method in the base page like the following code:
override protected void OnInit(EventArgs e)
{
//....
//....
if (!IsPostBack && Session["user"] == null)
{
if (Request.Cookies["CookieFromXXX"] != null)
{
HttpCookie cookie = Request.Cookies["CookieFromXXX"];
string userId = cookie.Values["userId"].ToString();
string pwd = cookie.Values["pwd"].ToString();
ApplicationUser user = ApplicationUser.RetrieveCurrentUserByLoginId(userId);
if (user != null user.Password == pwd)
{
Session["user"] = user;
}
}
}
base.OnInit(e);
}
Or you can add the above logic in the OnLoad method in the home page.
Step 4: Use the Session["user"] to determine the subscriber logged in or not
In any web page, you can check the Session["user"] to determine the subscriber logged in or not, see the following code:
if (Session["user"] != null)
{
//logged in already
//....
}
else
{
//haven't logged in yet
//....
}
Step 5: Expire the cookie when subscriber logout the website
Add the following code to expire the cookie when subscribers logout the website.
this.Session.Clear();
if (Response.Cookies["CookieFromXXX{0}"] != null)
{
//Response.Cookies.Remove("CookieFromXXX");
Response.Cookies["CookieFromXXX"].Expires = DateTime.Now.AddDays(-1);
}
Response.Redirect("./homepage.aspx");

It doesn't, by default in VS2005 your pages are compiled the first time someone requests them.

Hi All
I have the following element
<span id="Label2" style="display:inline-block;border-width:1px;border-style:Solid;width:200px;">Label</span>
(Actually this is the output of the ASP.NET Label Server Control)
I get two different outputs when I use IE and when I use FireFox browsers.
Has Anybody seen this.?
Thanks

Odd that an ASP.NET control would not adapt, but different styles from the same css between browsers is common.
