Namespace prefix asp on FormView is not defined - What is my Page Directive?

Using Microsoft Expression Web 4, I created a simple web page in which i use a ASP Connection to connect to a local Access DB. Below (at the bottom) is the source code for the entire page which works perfectly fine.

When I browse this web page (ASPX page) directly, everything works/renders fine.

However, a problem arises when I navigate to this page from a different web page. The browser states that this page contains an error:

Namespace prefix asp on FormView is not defined

Below this , another error is mentioned which states:

Unescaped '<' not allowed in attributes values

As I am inexperienced in ASP, I didn't realise I needed a Page Directive at the beginning. However, what would my page directive be?

My page is called 'Make a Booking.aspx'.

It's all HTML/CSS and a wee bit of JavaScript in parts. Here is the entire page.

You need to have page directory on top of the Asp page.

<%@ Page Title="YourTitle" Language="C#" AutoEventWireup="false" CodeBehind="YourCodeBehind.aspx.cs" Inherits="YourCodeBehindNamspace" %>

Also please check if your web server configured to use the .Net framework? It sounds like the ASP.Net ISAPI filter is not picking up and translating the page.

Within Microsoft Expression Web 4, under Site > Site Settings there is an option for Previewing web pages, using Microsoft Expression Development Server. It was set to the option:

For only PHP and ASP.NET web pages

To fix the problem, I had to select the second option:

For ALL web pages.

It effectively means that i'm previewing all my web pages (HTML and ASPX pages) from LocalHost.

It seems that you copied the FormView code from somewhere and pasted it in an .aspx file correct?

If so, a standalone aspx page should look like this. This limits the code you can use since there is no code behid file where more complex actions are handled.

<%@ Page Language="C#" %>

<!DOCTYPE html>
<html>
<head>
    <title>Demo</title>
</head>
<body>

    <form runat="server" id="form1">

        <asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource1">
            <ItemTemplate>

                <asp:Label ID="Label1" runat="server" Text='<%# Eval("column1") %>' /> 

                 or 

                 <%# Eval("column1") %>

            </ItemTemplate>
        </asp:FormView>

        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="MyConnectionString" SelectCommand="select * from mytable" />

    </form>

</body>
</html>

See these links for more info. But if you go and do more on an aspx page I would recommend creating a project in Visual Studio and work from there.
