Object reference error in UserControl's Load event

I have a UserControl that I declare programmatically as follows:
Dim userctrl as New rightside_portal()
The codebehind file for this UserControl looks like the following:
Partial Public Class rightside_portal : Inherits System.Web.UI.UserControl
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
Const renewurl As String = "http://www.renewingsite.com/"
Me.lblExpiresOn.Text = String.Format("IMPORTANT<br/>Your account is set to
expire {0}. To renew your membership, please ", "EXPIRATIONDATE")
Me.lnkRenew.NavigateUrl = renewurl
Me.lnkSaveToday.NavigateUrl = renewurl
End Sub
End Class
However, I receive the following error when I run the application:
Server Error in '/' Application.

I am pretty sure the problem has something to do with the fact that I am
declaring the UserControl in my codebehind rather than my *.aspx file, but I
am not quite sure what I need to do differently. If anyone can help me, I
would appreciate it. Thanks.

http://www.nathansokalski.com/you can't create a "new UserContorl();"
you need to use Page.LoadControl("~/controls/test.ascx");
Using "new" creates a new instance of the class, but doesn't instanticate
the aspx class. therefore lblExpires is never created and you end up with a
null reference.
