Chapter 6 pps 226-228 User Selected Theme

Featheriver · July 20th, 2008, 01:14 PM

I completed the Try It Out in Chapter 6, pps 226-228, Applying the User-Selected Theme.

I'm using C# and code behind.

When I tried Step 3 in the Try it Out on pagd 227 I get this error:
Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1518: Expected class, delegate, enum, interface, or struct

Source Error:

Line 16: }
Line 17: }
Line 18: private void Page_PreInit(object sender, EventArgs e)
Line 19: {
Line 20: HttpCookie preferredTheme = Request.Cookies.Get("PreferredTheme");

Source File: c:\BegASPNET\Site\App_Code\BasePage.cs Line: 18

I am totally new to ASP.NET 3.5 (or any other version of it). I can see from the error message that the problem is from the BasePage.cs file. (I'm following Imar's book to the bitter end.) So here is what the code in my BasePage looks like.

using System;
using System.Web;
public class BasePage : System.Web.UI.Page
{
  private void Page_PreRender(object sender, EventArgs e)
  {
    if (this.Title == "Untitled Page")
    {
      throw new Exception("Page title cannot be \"Untitled Page\".");
    }
  }
  public BasePage()
  {
    this.PreRender += new EventHandler(Page_PreRender);
    this.PreInit += new EventHandler(Page_PreInit);
  }
}
private void Page_PreInit(object sender, EventArgs e)
{
HttpCookie preferredTheme = Request.Cookies.Get("PreferredTheme");
if (preferredTheme != null)
{
Page.Theme = preferredTheme.Value;
}
}

I've looked all around everywhere I can think of to find an answer and solution to this error without success. I'm hoping to find out here. Bear in mind I need a clear simple understandable answer. Most of this stuff is all Greek to me. Thanks for any help.

Hi there,

Take a look at this:

public BasePage()
{
this.PreRender += new EventHandler(Page_PreRender);
this.PreInit += new EventHandler(Page_PreInit);
}
}
private void Page_PreInit(object sender, EventArgs e)
{

Notice the last } before private void Page_PreInit?

It shouldn't be there; right now it closes the BasePage class so the code that follows it is no longer in a class and this the compiler "Expect[s a] class, delegate, enum, interface, or struct".

Simply remove it and you're good to go.

Cheers,

Imar

Please help

Code:

BasePage

  

Public Class BasePage
    Inherits System.Web.UI.MasterPage

    Dim Title As String

    Private Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) _
        Handles Me.PreInit
        Dim preferredTheme As System.Web.HttpCookie = Request.Cookies.Get("PreferredTheme")
        If preferredTheme IsNot Nothing Then
            Page.Theme = preferredTheme.Value

        End If

    End Sub
    Private Sub Page_Prerender(
       ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender

        If Me.Title = "Untitled Page" Or String.IsNullOrEmpty(Me.Title) Then
            Throw New Exception(
                "Page title cannot be ""Untitled Page"" or an empty string.")
        End If



    End Sub
End Class

thanks
