Keep me logged in functionality in C# ASP.NET

Sometimes a user logs in to your website, comes back tomorrow and.... has to log in again. To avoid this problem i am providing option to keep you from having to enter your user name and password every time someone return. If someone check the 'Keep me logged in' box, a small cookie will create on your computer that will let us know who you are next time you login again.

Solution:-

First you have to create Cookie on login button click as follows :

protected void btnLogin_Click(object sender, System.EventArgs e)
{
    string Username = txtUsername.Text;
    string Password = txtPassword.Text;

//Create Cookie and Store the Login Detail in it, if check box is marked like this :-

    if ((CheckBox1.Checked == true))
  {
        HttpCookie createCookie = new HttpCookie("LoginDetail");
        createCookie.Values("Username") = txtUsername.Text.Trim();
        createCookie.Values("Password") = txtPassword.Text.Trim();
        createCookie.Expires = System.DateTime.Now.AddDays(1);

        Response.Cookies.Add(createCookie);
    }    
    Response.Redirect("Page Name");//Page Name on which you want to transfer your current page
}

Then you have check if cookie exists (is remember me marked), if yes fill the details like this on Page Load Event :-

protected void Page_Load(object sender, System.EventArgs e)
{
         if ((Response.Cookies("LoginDetail") != null))
 {          
        string uname = Response.Cookies("LoginDetail").Values("Username").ToString();
        string pass = Response.Cookies("LoginDetail").Values("Password").ToString();

    Response.Redirect("Page Name");//Page Name on which you want to transfer your current page
  }
}

That’s it!!…..Happy Programming...
