    Control out of context

    Hello everybody

    I`ve created a WebForms applications for learning purposes. I`ve placed two TextBoxes on my WebForm1 using the Visual Studio toolbox. The code is shown below :

    Code:
    <asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox>
    <br />
    Last Name:
    <asp:TextBox ID="txtLastName" runat="server"></asp:TextBox>
    <br />
    Now in the corresponding WebForm1.aspx.cs coding file I`m trying to export the functionality of these two controls by creating the attribute FullName

    Code:
    public string FullName
    {
    get { return txtFirstName.Text + " " + txtLastName.Text; }
    }
    Unfortunately, when I compile my code I get the error :

    Code:
    Error	1	The name 'txtFirstName' does not exist in the current context
    Shouldn`t the control be in context since I`m placing it on the same WebForm1 as the corresponding cs file?

    Check that the following is in your project files...
    In the WebForm1.aspx on top.
    Code:
    <%@ Control Language="cs" AutoEventWireup="false" CodeBehind="WebForm1.aspx.cs" Inherits="[Namespace].WebForm1" %>
    and in WebForm1.aspx.cs.
    Code:
    Namespace [Namespace]
        Partial Public Class WebForm1
    Then dbl check that the Autogenerated WebForm1.aspx.designer.cs contains the following..
    Code:
    Namespace [Namespace]
        Partial Public Class WebForm1
    
            Protected WithEvents txtFirstName As Global.System.Web.UI.WebControls.TextBox
