Hi,

    <br /><br />
    ************ -
    <asp:radiobuttonlist id="************" runat="server">
      <asp:listitem value="Male" />
      <asp:listitem value="Female" />
    </asp:radiobuttonlist>
    Please select the destination you would like details on:
    <asp:dropdownlist id="Destination" runat="server">
      <asp:listitem value="Madrid" />

So, runat="server" must be placed inside the form tag.
<form id="formname" method="post" runat="server">

Hi,

If I put <form id="formname" method="post" runat="server">, the current page (holidaypage.aspx) won't be able to forward to holidayresponse.aspx when I click on submit button. It just stay on the current page when I click on submit!

Sorry, I have not seen that you send the form to another page.
Well, ASPX page is powerful when the page is posted to itself. In your case - you just send the form to some page, so, you don't need aspx page, you can use .html page.

Hi,

Is there anyway that I can redirect to the page(holidayresponse.aspx) from holidaypage.aspx page without changing it to .html? However, this code example is from the Wrox book. This means that the book's code have bugs?

hi
I have this problem too.
I guess that there is something wrong with the framework SDK.In this book,the author use beta 2(v1.0.29.14).But i use v1.1.

Hi,

So how can we correct this problem?

NotNowJohn · July 10th, 2003, 11:25 AM

Well, If you insist...
on holidaypage.aspx you have to add this lines at the top of page:

Code:

<%@Page language="c#"  ClassName="HolidayPage" %>
<script  runat="server" >
public string HPFullName
   {
      get
      {
         return FullName.Text;
      }
   }

public string HPAddress
   {
      get
      {
         return Address.Text;
      }
   }

public string HPSex
   {
      get
      {
         return ************.SelectedItem.Text;
      }
   }

public string HPDestination
   {
      get
      {
         return Destination.SelectedItem.Text;
      }
   }


  void Page_Load()
  {
    if (IsPostBack)
    {    
        Server.Transfer("holidayresponse.aspx");
    }
  }
</script>

On the holidayresponse.aspx you have to add at the top of page:

Code:

<%@ Reference Page="holidaypage.aspx" %>
 HolidayPage hp;
void Page_Load()
  {

        hp = (HolidayPage)Context.Handler;
    Response.Write("<b>Name:</b> " + hp.HPFullName + "<br />");
    Response.Write("<b>Address:</b> " + hp.HPAddress + "<br />");
        Response.Write("<b>************:</b> " + hp.************ + "<br />");
        Response.Write("<b>Destination:</b> " + hp.HPDestination + "<br />");
  }
</script>

That't it! ;)

Hi NotNowJohn,

Sorry for troubling u again. I cpoied and pasted your code but I got a compilation error saying that

Compiler Error Message: CS1014: A get or set accessor expected

Source Error:

Line 4: public string HPFullName
Line 5: {
Line 6: get
Line 7: {
Line 8: return FullName.Text;

Hi,

The way I see it now, you have two options if you want to submit a .NET form to another page. You can't do it if you put the runat="server" attribute to the form element since .NET forms ALWAYS post back results to themselves.

If you will use the code that was given to you above, you need to add the following to each property block to compile it properly:

    public string HPFullName
    {
       get {
          return FullName.Text;
       }
       set {
          FullName.Text = value;
       }
    }

The other way you can submit to a different page would be to omit the runat attribute from the form and use HTMLControls instead. These are just plain html elements like <input> or <select>, but they all have the runat attribute, like so:

    <input type="text" id="FullName" runat="server" />

They work basically the same way as webcontrols and you will still be able to access their properties individually through codebehind. Taking your original code, it would become something like the following:

<html>
<head>
  <title>Holiday page</title>
</head>
<body>
  <form action="holidayresponse.aspx" method="post">
    <h1>Feiertag Holidays</h1>
    Please enter your details here.
    <br /><br />
    Name:<input type="text" id="FullName" runat="server" />
    <br /><br />
    Address:<textarea id="Address" rows="5" runat="server" />
    <br /><br />
    ************ -
    <input type="radio" name="************" value="Male" runat="server" />
    <input type="radio" name="************" value="Female" runat="server" />
    Please select the destination you would like details on:
    <select id="Destination" runat="server">
      <option value="Madrid">Madrid</option>
      <option value="Barcelona">Barcelona</option>
      <option value="Lisbon">Lisbon</option>
      <option value="Oslo">Oslo</option>
      <option value="Prague"></option>
    </select>
    <br /><br />
      <input type="Submit">
    <input type="Reset">
  </form>
</body>
</html>

Cheers!
