  Two days ago I begined to study this book and then meeted a problem .
  After I executed the holidaypage.aspx with webbrower ,it said that:"Control 'address' of type 'TextBox' must be placed inside a form tag with runat=server ".
  But if place "runat=server" into the form tag of "hoidaypage.aspx",my brower will not auto go to the "holidayresponse.aspx" after click submit button.It also display "hoidaypage.aspx". The point is that I want it to auto display "holidayresponse.aspx" after click submit button!

Below is the origin code:
-------------------------------------------------------------------
1.holidaypage.aspx:
<html>
  <head>
    <title>Holiday page</title>
  </head>
  <body>
   <form action="holidayresponse.aspx" method="post">
      Please enter your name:
      <asp:textbox id="fullname" />
      <br /><br />
      Please enter your address:
      <asp:textbox runat="server" id="address" rows=5 textmode="multiline" />
      <br /><br />
      please choose ************:
      <asp:radiobuttonlist id="************" runat="server">
        <asp:listitem id="option1" value="Male" />
        <asp:listitem id="option2" value="Female" />
      </asp:radiobuttonlist>
      <br /><br />
      Please select the destination you would like details on:
      <asp:dropdownlist id="destination" runat="server">
         <asp:listitem value="madrid"/>
         <asp:listitem value="oslo"/>
         <asp:listitem value="prague"/>
         <asp:listitem value="lisbon"/>
      </asp:dropdownlist>
      <br/><br/>
      <input type="Submit">
        <input type="reset">
    </form>
</body>
</html>

2.holidayresponse.aspx:
<script runat="server" language="vb">
  Sub Page_Load()
        response.write("<b>Name:</b>"+request.form("fullname")+"<br/>")
        response.write("<b>Adrress:</b>"+request.form("address")+"<br/>")
        response.write("<b>************:</b>"+request.form("************")+"<br/>")
        response.write("<b>Destination:</b>"+request.form("destination")+"<br/>")
   End Sub
</script>
<html>
  <head>
    <title>Holiday page</title>
  </head>
  <body>
    <br/><br/>

Asp.net pages don't work the same way classic ASP pages did. The form will always be posted back to the original page. It was created that way to act more like Windows forms.

If you want move to a different page, you will have to pass those values a different way like in a querystring. However, in my opinion, this kind of defeats the purpose of using .net.

if you are passing values to a different page you can't retrieve that information by using asp.net controls. instead, you need to use the Params collection from the HTTPRequest class.

ex. Request.Params("fullname")

Alternatively the old ASP collections are still supported.
eg. Request.QueryString("fullname")
Request.Form("fullname")
