Cant Find Dark Green

Derrick T. Davidson · November 9th, 2011, 10:38 PM

Hi I am a newbie please bear with me,

I have succesfully done all the exercises in the book until the end of chapter six. Now I try to load the pade and I get the error below. I have copied the code from the sample chapters to my application but the same message keeps showing.

What am I doing wrong?

Hi Derrick,
The error message said you have not Theme's by "Dark Gray" name. As i know the correct name is 'DarkGray'(whitout space) in resource in the book. Please look at Theme folder and and look for right name of theme.
I hope this help you.

Thanks Morteza

My Solution Explorer shows:
App_Themes

Folder> DarkGrey
Folder> Images
SubFolder> Header.jpg
File> DarkGrey.css

The same folders and files for Monochrome are also shown similar to this in the App_Themes folder.

Please note "Grey" is shown not "Gray" and I am using Visual Studio Ultimate?

OK you should use 'DarkGrey' in your code instead of 'Dark Grey'(with space).
any doubt please comment.

I have no spaces between the name "DarkGrey". Even if I try to run the code from the Chapter six source file downloaded with the book I get the same message?

This error said that : you use 'Dark Grey' in your code. Did you use it in :

Code:

switch (Page.Theme.ToLower())
{
case âdarkgreyâ:
Menu1.Visible = false;
TreeView1.Visible = true;
break;
default:
Menu1.Visible = true;
TreeView1.Visible = false;
break;
}

?

also in web.config file check this :

Code:

<pages theme=âDarkGreyâ>
...
</pages>

Did you enter DarkGrey like the theme name in Theme folder?

MasterPage Code:

<asp:DropDownList ID="ThemeList" runat="server" AutoPostBack="True">
<asp:ListItem>Monochrome</asp:ListItem>
<asp:ListItem>DarkGrey</asp:ListItem>

Web Config = <system.web>
<pages theme="Monochrome" styleSheetTheme="Monochrome"/>
The book says this is the default page

I cant see anywhere there is a space???

In 'Edit' menu select 'Find and Replace' sub-menu and then select 'Find in Files'; In Window that appears in 'Find what' field type 'Dark Grey' and for look in : select Entire solution and click Find all.
