Ch 13: page 445

papadan · April 15th, 2017, 12:03 PM

For Chapter 13 - Displaying and Updating Data, page 445, I added a new web.config file to my Managements folder with:

Code:

<pages theme = ""

However, I am still getting the image in the <nav> element from the Monochrome.css file that's in my Themes folder.

What am I doing wrong?

Is the theme still applied through your custom code based on the user's selection?

Check out the HTML source for the page in the browser and look for links to your theme. That would confirm a specific theme is still in use.

Cheers,

<<Is the theme still applied through your custom code based on the user's selection? >>

I don't have it set up as custom code (maybe?) - I am linked to the theme as Theme="MainTheme" In other words, I am only using Monochrome theme. I know I don't have to (based on a previous post we discussed) - but I have it in place currently. The other theme isn't loaded nor does the user have any options to switch.

Maybe that's the problem? Maybe the book instructed me to set things up in a "Custom Code" theme fashion. And I didn't.

In any case, to answer your second question:

<<Check out the HTML source for the page in the browser and look for links to your theme. That would confirm a specific theme is still in use.>>

Yes, the specific theme is still in use:

Code:

<head>
   <link href="../App_Themes/MainTheme/Monochrome.css" 
         type="text/css" rel="stylesheet" />
   <title>Good News Productions - Genres</title>
</head>

I will add that my web.config for the other master page is outside (at the root) - whereas my web.config for the new master page is in the Management folder.
Should my web.config for my monochrome theme be inside its own folder too?

Oh, I see, this is about the management folder. I missed that on your first post.

The following in web.config in your Management folder should clear out the theme:
<?xml version="1.0"?> <configuration> <system.web> <pages theme="" /> </system.web> </configuration>Is it not doing that?

No, it is not working. I have a web.config with that code in my Management folder, but it is not clearing out (or disabling) the theme from my other web.config

Can you post an image of your solution explorer online somewhere (you can't add an image as part of a post here so you'll need to upload it somewhere). Make sure it shows the root of the with the App_Code and Management folders expanded. I just tried it locally on a copy of Planet Wrox and it works for me, so it must be something in your setup.

Also: are the pages in the Management folder using their own master page? Can you post the code for the following:

1. Code behind of a page in the Management folder
1. Markup of a page in the Management folder
1. Code of BasePage.vb/cs from App_Code

Cheers,

The only place i could think of to download my image was on Face Book:

Please let me know if you were able to see the image.

That all looks good to me. Two more requests:

1. Can you post the code for web.config in the Management folder?

2. Can you post the code for Management.master

If those look fine too, I am not sure what's going on. If you're able to upload a zipped copy of the site, I'll download it and take a look.

Cheers,

You'd think I would know this - but how do I attach my zip file here?

<<Can you post the code for web.config in the Management folder?>>

Code:

    <system.web>

I don't see an option anywhere to "Manage Attachments" ??
