title: The name 'xxx' does not exist in current context user control
body: <p>I have this statemen at the beginning:</p>
  
  <pre><code>&lt;%@ Control Language="C#" AutoEventWireup="true" CodeFile="ucCreditCard.ascx.cs"
      Inherits="UserControls_Common_ucCreditCard" %&gt;
  </code></pre>
  
  <p>in ucCreditCard.ascx.cs I have this:</p>
  
  <pre><code>using System;
  using System.Text;
  using System.Text.RegularExpressions;
  using System.Collections;
  using System.Configuration;
  using System.Data;
  using System.Linq;
  using System.Web;
  using System.Web.Security;
  using System.Web.UI;
  using System.Web.UI.HtmlControls;
  using System.Web.UI.WebControls;
  using System.Web.UI.WebControls.WebParts;
  using System.Xml.Linq;
  
  public partial class UserControls_User_ucCreditCard : System.Web.UI.UserControl
  {
  //
  }
  </code></pre>
  
  <p>When I try to reference any of the simple control like Textbox etc, I always get control 'xxx' does not exist in current content. What can be the problem?</p>
  
  <p>Thanks in advance :)</p>
