Code behind file not recognizing controls in *.ascx

I have a QuestionControl.ascx and a QuestionControl.ascx.cs code behind file I copied to a new project. When I build the project any references in the code behind file to controls declared in the ascx gives me this error:

'QuestionControl' does not contain a definition for 'rdbtnlstQuestion1' and no extension method 'rdbtnlstQuestion1' accepting a first argument of type 'QuestionControl' could be found (are you missing a using directive or an assembly reference?)

This is at the top of my *.ascx:

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

I've also tried CodeBehind:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="QuestionControl.ascx.cs" Inherits="QuestionControl" %>

This is the top of my class in the codebehind file, it is not contained in a namespace:

public partial class QuestionControl : System.Web.UI.UserControl
{
Solution

  • Try deleting your designer file. VS.NET should recreate it for you when you open the ascx file. I've had problems like this in the past where the designer gets out-of-sync for some reason, and deleting it usually fixes the problem.
