Question

using code blocks in head content and link tags

Answer 1

A:

Ok I got it working by using some inline code. Inline code is not my my first choice but I wanted a solution that worked in mvc as well. Here's what I came up with:

<head runat="server">
    <title>My Test App <title>
    <script language="CS" runat="server">
        void Page_Load(object sender, System.EventArgs e) 
        {
            string sTheme = String.IsNullOrEmpty(Page.Theme) ? Page.StyleSheetTheme : Page.Theme;
            litFacIcon.Text = "<link rel=\"shortcut icon\" href=\"/App_Themes/" + sTheme + "/images/bookmark.ico\" type=\"image/x-icon\"/>";
        } 
    </script>
    <asp:Literal ID="litFacIcon" runat="server"></asp:Literal>
</head>

This wouldn't work because you marked it as runat="server"

try this instead

<link rel="shortcut icon" href="<%=ResolveUrl(string.Format("~/App_Themes/{0}/images/bookmark.ico", Page.Theme)) %>" type="image/x-icon"/>

Does not work either. Still get the error The Controls collection cannot be modified because the control contains code blocks (i.e. ).

can you tell me what your entire <head> tag looks like?

hunter 2010-02-02 19:02:52

if you have runat="server" in your head tag and you add any other controls to it you couldn't do what I suggested

@hunter: Do you know why runat="server" makes it fail? I would think it would be the other way round

tags marked with `runat="server"` can't be modified inline since ASP.Net is managing that control.

+1 A:

jeremy,

try creating an html helper such as:

public static string SetThemeIcon(this HtmlHelper html, string themename)
{
    var filePath = VirtualPathUtility.ToAbsolute("~/App_Themes/" + themename + "/images/bookmark.ico");
    return "<link rel=\"shortcut icon\" href=\"" + filePath + "\" type=\"image/x-icon\"/>";
}

then, in your view or master page, simply reference it as so:

<%= Html.SetThemeIcon("test") %>

or as in your case above (in mvc):

<%= Html.SetThemeIcon(String.IsNullOrEmpty(Page.Theme) ? Page.StyleSheetTheme : Page.Theme) %>

hope this helps...
