Themes problem

knutz0r · March 5th, 2015, 11:46 AM

I just finished the themes part with the dropdownlist. the problem is the only theme that is working is monochrome. i verified the code and it s exactly as in the book. when the page loads monochrome is preselected and loads. when i try to select darkgrey a postback is made and the "darkgrey" in the ddl doesn't remain selected instead monochrome reselects itself. what code should remain in the web.config file at the <pages> tag? this is what i have now "<pages theme="DarkGrey"></pages>" but still monochrome only works. please help!

LE: The "Monocrome" theme remains selected always in the DDL but if i load a page from the demos folder it has the darkgrey skin even though the "monchrome" is selected...

Hi there,

Have you tried debugging your code? Can you see the cookie being set? Maybe this helps?

It might be a cookie setting then. Try clearing your cookies in Chrome (in case you had an old cookie with outdated information) and check if you have any cookie blockers installed.

Cheers,

You don't have to clear your cookies at all, unless you stored a value earlier that no longer matches the theme.

You must be using a more recent version of VS than the book expects. Things have changed quite a bit between versions, so you need to either provide the jQuery mapping or disable unobtrusive validation by adding the following appSetting to web.config:

Code:

<appSettings>
  <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

Cheers,

You should try with another browser which suit best.
