cannot resolve symbol

Question

i have made a simple table (lets call it volunteers), but when i want to call it in my code behind Visual studio can not recognize it. The error is cannot resolve symbol 'volunteers'.

here is the code:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="root_VerifyUsers.aspx.cs" 
     MasterPageFile="~/Root.Master" %>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

               <p>
                   <asp:Table runat="server" ID="volunteers" ForeColor="Green" Width="100%" Height="85%"  BorderColor="Red"></asp:Table>

                   <asp:TableHeaderCell ID="NationalId" runat="server">National Id</asp:TableHeaderCell>
                   <asp:TableHeaderCell ID="Email" runat="server">Email</asp:TableHeaderCell>
               </p>

</asp:Content>

that is behind code:

public partial class RootVerifyUsers : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {


        TableRow tr = new TableRow();
        TableCell fname = new TableCell();

        TableCell NationalId=new TableCell();
        tr.Cells.Add(NationalId);
        volunteers.Rows.add(tr);

    }

}

Cannot resolve what symbol? That's not the whole error. Why wouldn't you post the whole error? Trying to make it a challenge? — Ant P, Sep 18 '13 at 10:21

I have edited your title. Please see, "[Should questions include “tags” in their titles?](http://meta.stackexchange.com/questions/19190/)", where the consensus is "no, they should not". — John Saunders, Sep 18 '13 at 10:40

You have asp:TableHeaderCell with an id of NationalId and a local variable called NationalId:

TableCell NationalId=new TableCell();

That isn't going to work... Change one of them to start with..

Also, have a look at the examples on MSDN here, to correctly structure your <asp:Table...

What did you change NationalId to, and what is the error message? – Joe Ratzer Sep 18 '13 at 10:37
I would also put the tableheadercells inside the table. – Joe Ratzer Sep 18 '13 at 10:38

Your TableHeaderCell should be inside Table tag

<asp:Table runat="server" ID="volunteers" ForeColor="Green" Width="100%" Height="85%"  BorderColor="Red">

               <asp:TableHeaderCell ID="NationalId" runat="server">National Id</asp:TableHeaderCell>
               <asp:TableHeaderCell ID="Email" runat="server">Email</asp:TableHeaderCell>
</asp:Table>

cannot resolve symbol
