I wanted to add a Literal tag to a page like in this article:
http://www.odetocode.com/Code/82.aspx
But I keep getting a parser error on my page:
Parser Error Message: The base class includes the field 'stylesheet', but its type (System.Web.UI.WebControls.Literal) is not compatible with the type of control (System.Web.UI.HtmlControls.HtmlGenericControl).
Here's my code:
-- from .aspx:
<LINK href="http://links.10026.com/?link=<asp:Literal id="stylesheet" runat="Server" />" type="text/css" rel="stylesheet">

I would have snipped the code-behind, but I figured I'd end up snipping the offending line... I'd be happy to provide more info if required.
J<LINK href="http://links.10026.com/?link=" type="text/css" rel="stylesheet" id="stylesheet" runat="server" />
Protected WithEvents stylesheet As System.Web.UI.HtmlControls.HtmlGenericControl' code:
stylesheet.Attributes.Add("href", "whatever value")
I think you're confusing the parser with nested tags. Try to make stylesheet a string instead of a literal and inject its value using <%= %>.
Even better, make the LINK tag runat=server (and declare it as a HtmlGenericControl in the code-behind) and set its properties using the Attributes collection.
Thank you both, its working now. I am making the link runat=server.
And when I took the literal out of the <link/> it also worked, so at least I know what the problem was!
Cheers,
J
