aspx_beginners thread: Code Behind

Message #1 by "Marni Alvarez" <marni@f...> on Tue, 23 Apr 2002 10:05:55 -0700

MessageHi there.

I am reading the book Professional ASP.NET version 1.0 and am trying to do
the code behind example on pages 29-30.  But I am getting the following
error:
Compiler Error Message: BC30451: Name 'YourName' is not declared.

I tried adding the Name="YourName" property, but that didn't work either.
The code is right from the book. Any ideas?

' TestASPX.aspx
 <@Page Language="VB" Inherits="Ch1CodeBehind"
Src="Components\Ch1CodeBehind.vb" %>
<html>
  <body>
    <form runat="server">
        Enter Your Name: <asp:TextBox ID="Name" Runat="server" />
        <br />
        Press Button: <asp:Button OnClick="btn_Click" Runat="server"
Text="Press Me" />
        <br />
        Your Name Is: <asp:Label ID="YourName" Runat="server" />
    </form>
  </body>
</html>

' Ch1CodeBehind.vb
Imports System
Imports System.Web.UI
Imports System.Web.UI.WebControls

Public Class Ch1CodeBehind
  Inherits System.Web.UI.Page
  Public Sub btn_Click(Sender As Object, E As EventArgs)
    YourName.Text = Name.Text
  End Sub
End Class

Thanks for your help,
Marni

Looks to me like they missed out a couple of lines. In the VB file the class
needs to know about the controls on the page (in the aspx file). So add the
following within the class and you should be OK...

  Public YourName As Label
  Public Name As TextBox

Looks like 'YourName' is not a valid name of control... check this name - 
maybe you yse ordinary HTML control instead of WEB Server Control ? In that 
case it will be also anavalible.

Cheers.
