Question

This is a pretty simple question as i am new to asp.net i am trying to develop a contact us page and i am getting the following error.

“Control ‘ContentPlaceHolder1_nameBox’ of type ‘TextBox’ must be placed inside a form tag with runat=server”

The following is my code so far for that page.

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="ContactUs.aspx.cs" Inherits="Craigavon_Aquatics.ContactUs" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<h2>
    Contact Us</h2>
<p>
    Please fill in the form below to contact us.</p>

<p>
    &nbsp;</p>

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<table style="width: 100%">
    <tr>
        <td>
            Name: (Required)</td>
    </tr>
    <tr>
        <td>
<asp:TextBox ID="nameBox" runat="server" Width="278px"></asp:TextBox>                
        </td>
    </tr>
    <tr>
        <td>
            Email: (Required)</td>
    </tr>
    <tr>
        <td>

        </td>
    </tr>
</table>
</asp:Content>

Answer 1

Either place a wrapper <form runat="Server"> in your master page around the contentplaceholder, or on that page inside the <asp:Content> tag add a <form runat="server"> that surrounds your current content.

Site1.Master

<form runat="server">
  <asp:ContentPlaceHolder ...></asp:ContentPlaceHolder>
</form>

-OR-

ContactUs.aspx

<asp:Content ...>
  <form runat="server">
    ...existing HTML code...
  </form>
</asp:Content>
