Sure, I can help you with that. Here are the steps on how to create a remember me check box to remember session until user logout explicitly:

  1. Create a new ASP.NET Web Forms project.
  2. Add a CheckBox control to the form.
  3. In the code behind file, add the following code:

VB.Net

Protected Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox1.CheckedChanged
    ' If the checkbox is checked, set the remember me cookie.
    If CheckBox1.Checked Then
        Dim cookie As HttpCookie = New HttpCookie("RememberMe")
        cookie.Value = "1"
        cookie.Expires = DateTime.Now.AddDays(30)
        Response.Cookies.Add(cookie)
    Else
        ' If the checkbox is unchecked, delete the remember me cookie.
        Dim cookie As HttpCookie = Response.Cookies("RememberMe")
        Response.Cookies.Remove(cookie)
    End If
End Sub
  1. Run the project. When you check the checkbox, a cookie will be set that will remember the user's session for 30 days. When the user logs out, the cookie will be deleted.

Here is an explanation of the code:

  • The CheckedChanged event is raised when the Checked property of the CheckBox control changes.
  • The HttpCookie class represents a cookie.
  • The Value property of the HttpCookie class sets the value of the cookie.
  • The Expires property of the HttpCookie class sets the expiration date of the cookie.
  • The Cookies property of the Response object gets the collection of cookies for the current request.
  • The Add method of the Cookies property adds a cookie to the collection.
  • The Remove method of the Cookies property removes a cookie from the collection.

Hi John, 

Simply pass true as second parameter when emitting the authentication cookie:

FormsAuthentication.RedirectFromLoginPage(Username, true)

This will create a persistent authentication cookie on the client whose expiration is handled by the timeout property in your web.config:

<forms
   loginUrl="~/login.aspx"
   defaultUrl="~/default.aspx"
   protection="All"
   timeout="3600"
</forms>
