I want to allow users of my site to choose what CSS file the site is rendered with. I'm assuming I'll be storing that preference in cookies (since not all visitors are registered in the dB) and also also assuming that I'll applying that preference page-wise in the header.

How can I pass that variable/string from the codebehind forward into the header of the .aspx page? I've tried a line such as...

<link href="<%= CSSpreferenceString %>" type=text/css rel=stylesheet>

...but Visual Studio complains about this and highlights the <% and %> in yellow. Is there anything special about the declaration of things you want to use in the .aspx instead of the codebehind?

 

in the head put

<link id="selStylesheet" rel="styleSheet" runat="server"></link>

in the codebehind

Protected selStylesheet As System.Web.UI.HtmlControls.HtmlGenericControl

in the Page.Load event put

Private Sub Page_Load (ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Get cookie value
selStylesheet.Attributes.Add("href", thevalue)
End Sub

u could put select case statements so that the selection stored inthe cookie isnt the url to the stylesheet but more friendly, and get the url from whereever... from constants in the code, or from appSettings in the web.config

Thats one way of doing it.

 

the trick here is the Runat="server"

and dimming a usuable UI object in the codebehind.

means u have access to it via code

 

Thanks SCOSaltire. I posted the same question on another Forum and a poster over there suggested using a Literal control. Probably a "six of one, half a dozen of another" situation! Thanks, though -- I didn't know the System.Web.UI.HtmlControls.HtmlGenericControl thing existed!

 

aye, that generic control is often used in creating User Controls

no probs
