The name 'xxx' does not exist in current context user control
<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>
