Chapter 7 Compilation Error

bshay · September 16th, 2003, 11:40 AM

In the event.aspx example, I get the following error: BC30451: Name 'Message' is not declared on line 4.

I get the same error in chapter 2's datacontrol2.aspx example stating that DataGrid1 is not declared.

Am I missing something?

What you are missing is posting some code here ;)

I don't have the book here, so it's hard to tell what the problem can be. If you post the relevant part of the code, it's easier for us to see what the problem is.

Cheers,

Imar

Sorry, This is my first time posting and was trying to keep it short. Here is my code:

<script language="vb" runat="server">
    Sub ClickHandler(Sender As Object, E as EventArgs)
        If ExtraInfoBox.Checked then
            Message.Text = "<br /><br />You will hear from us shortly"
        Else
            Message.Text = "<br /><br />You will not receive any further" & _
                " information from us"
        End If
    End Sub
</script>

<html>
    <head>
      <title>Server-side event processing example</title>
    </head>
    <body>
      <form runat="server">
        <asp:CheckBox id="ExtraInfoBox" Text=
        "Click here to receive extra information" Runat="server" />
        <br /><br />
        <asp:Button id="Button1" Text="Click Here to Submit" onclick="ClickHandler" runat="server"/>
      </form>
    </body>
</html>

I figured out my error! When typing in the code I skipped the following line:

<asp:Label id=Message" runat="server"/>

I didn't realize this line was actually declaring the objects that could be referenced in the script above.
