Hi all,

I am developing a custom module in DNN 6.  I would like to know how I can have two module css files and switch between them depending on the user logging in.

Example: User A logs in.  I set the module.css file to a blue style (module_blue.css).  User B logs in, I set the module.css file to a red style (module_red.css).

Further information: I have a custom field in the user-profile that determines which style should be used.  So after the user logs into the DNN site and navigates to the page with the custom module on it, the module will know which module.css to use.

How would I achieve this in code?

Thanks for any help!

I've managed to solve this by using the following code on View.ascx Page_Init()

'Change the stylesheet depending on a property setting of the user's profile

            Dim cssStyle As HtmlLink = New HtmlLink()
            cssStyle.Attributes.Add("rel", "stylesheet")
            cssStyle.Attributes.Add("type", "text/css")

            Select Case yourSetting
                Case UseRedCSS
                    cssStyle.Href = "/DesktopModules/yourModule/red.css"
                Case UseBlueCSS
                    cssStyle.Href = "/DesktopModules/yourModule/blue.css"
                Case Else
                    cssStyle.Href = "/DesktopModules/yourModule/green.css"
            End Select
            Page.Header.Controls.Add(cssStyle)


The only thing I would suggest improving is the path to the .css files.  I would prefer a relative path but I'm not sure what that looks like.  This gets loaded after the module.css so it will override any styles in the module.css file.

Another approach would be to have your custom module emit a wrapping div round all the content and give it a class name that is generated in the code.

This would:
- work in all your controls, not just the view.
- allow you to target the generated class in standard module/portal etc css files.
Best wishes,
