Switching Themes

allken · September 16th, 2011, 10:24 AM

After having gone through the Book to about Ch 10 I now discover trouble in switching Themes.
The default page comes up in darkGrey while showing Monochrome in the DD List (lstPreferredTheme) .When making the other choice the page still remains in DarkGrey.

All code appears to be correct.
Has anyone any idea of a solution?

Hi there,

Did you remove the styleSheetTheme from the web.config file?

Hi Imar,
Yes - that code is removed.
web.config code is

Code:

 
<add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
<add assembly="System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/></assemblies>
</compilation>
<pages theme="Monochrome">
<namespaces>
<clear/>
<add namespace="System"/>
<add namespace="System.Collections"/>

In that case, can you post the full code for the master page (code behind and markup), the ASPX page you're testing this on (code behind and markup) and the BasePage from the App_Code folder?

Cheers,

Imar

Imar,
Thank you for quick reply.
In the meantime I 've played around with the code in an effort to solve the problem.
Never the less, here is the code. The Inherits appears wrong so I want to follow this before I return with the remaining code.

Code:

 
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPages_MasterPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder> 
<link href="../Styles/Styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="form1" runat="server">
<div id="PageWrapper">
<div id="Header"><a id="A1" class="HeaderLink" href="~/" runat="server"></a></div>
<div id="MenuWrapper">Menu Goes Here</div>
<div id="MainContent">
<asp:ContentPlaceHolder ID="cpMainContent" runat="server">
</asp:ContentPlaceHolder>
</div>
<div id="Sidebar">
Select a Theme <asp:DropDownList ID="lstPreferredTheme" runat="server" 
AutoPostBack="True">
<asp:ListItem>Monochrome</asp:ListItem>
<asp:ListItem>DarkGrey</asp:ListItem>
</asp:DropDownList>
</div>
<div id="Footer">Footer Goes Here</div>
</div>
</form>
</body>
</html>

cheers

Are you following the book with Visual Studio / VWD 2010? The inherits statement looks fine (folder name + file name) but you can only tell if it's really valid by looking at the code behind.

Imar,
I think I've got it
i use VWD 2008 Exp with IE 8 +vista

Earilier I tried this on XP where the master vb code behind appeared as Partial Class MasterPage, against Vista giving

Code:

 
Partial Class MasterPages_MasterPage

However besides that I ended up with a 2nd MasterPage.master in the root of the Site!! Don't know why.

Thanks for your excellent book and help.

Cheers,

Allan

I don't think it's a Vista versus XP issue. It could be that the behavior has changed in VS 2008 SP1. When I add a new master page to a subfolder it sets the Inherits attribute to FolderName_MasterPage name. I don't have an installation of VS 2008 without a Service Pack here so I can't check the behavior, and I don't recall how it was before SP1.

It could also be that you initially created the master in the root and then moved the file to a subfolder. That wouldn't change the Inherits attribute.

But are the problems fixed now? Do you see the correct theme appear?

Imar,
Yes thank you, everything seems to be working correctly now.
I think it must have been due to duplicate master pages in the Site.

One thing I did notice on re-starting is that banner .ascx shows in Design view while ContactForm does not? Is this normal.

Cheers

The disappearing form is a bug in VS 2008, descibed here:

Chapter 10 - Ajax try it out
