The name 'xxx' does not exist in current c

Question

I have this statemen at the beginning:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ucCreditCard.ascx.cs"
    Inherits="UserControls_Common_ucCreditCard" %>

in ucCreditCard.ascx.cs I have this:

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
{
//
}

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?

Thanks in advance :)

Answer 1

Hope You are missing the designer file, as these errors mostly occur only in such cases, Right click and convert to web application. should do the trick.

Also do check that its the same as the partial class defined in your .cs file

Answer 2

Here the solution. You missing to declare the project.

using System.Xml.Linq;
namespace YouProjectName
{
public partial class UserControls_Common_ucCreditCard : System.Web.UI.UserControl
{
//
}
} // end of namespace.

Answer 3

• This issue for me was caused by another error in the application
• I tried rebuilding the solution and was getting only this error and no others
• So I rebuilt just the project with the problem
• Another error appeared
• I fixed this - turns out it was blocking correct compilation of the user control
• Now works fine!

Answer 4

select "Convert to web application" it will create new .aspx.designer.cs file. Then Build would resolve the problem

Answer 5

To illustrate what V4Vendetta sayed ther is an exemple inyour case with a dropDownList.

UserControls_Common_ucCreditCard.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ucCreditCard.ascx.cs"
    Inherits="UserControls_Common_ucCreditCard" %>

//Exemple with a Drop down list
<asp:DropDownList ID="drpMain" runat="server" Width="200px" Visible="true">

ucCreditCard.ascx.designer.cs

    //Namespace must be the same in ucCreditCard.ascx.designer.cs and in ucCreditCard.ascx.cs
namespace NameOfYourProject {
                        public partial class UserControls_User_ucCreditCard {

                            protected global::System.Web.UI.WebControls.DropDownList drpMain;
                    }
}

ucCreditCard.ascx.cs

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;


namespace NameOfYourProject
{
public partial class UserControls_User_ucCreditCard : System.Web.UI.UserControl
{
// You can refer drpMain
}

Answer 6

You must have changed the name of your file but did not update the name of your class:

You have:

public partial class UserControls_User_ucCreditCard : System.Web.UI.UserControl
{
//
}

should be

public partial class UserControls_Common_ucCreditCard : System.Web.UI.UserControl
{
//
}

as indicated in the .aspx portion of your code.
