  • 0

I have created a new Web project (.Net 3.5) and I’ve removed the original Default page in favour of creating a Master page and then recreating a Default with Master page. All worked lovely. Now, when I add my controls inside of the ContentPlaceHolder on the Default page, I get compiler errors when I try to access the controls from the CodeFile:

Error 4 ‘_Default’ does not contain a
definition for ‘FirstName’ and no
extension method ‘FirstName’ accepting
a first argument of type ‘_Default’
could be found (are you missing a
using directive or an assembly
reference?)

My declaration of the control:

<asp:TextBox runat="server" ID="FirstName" />

Any ideas?

EDIT

Page declaration:

<%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

Code-behind:

string firstname = FirstName.Text;

    I managed to get this working by changing CodeFile to CodeBehind.

    Working:

    <%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="_Default" %>

    Not working:

    <%@ Page Title="" Language="C#" MasterPageFile="~/Master/MasterPage.Master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
