Question

This is my code:

Page.Header.Controls.Add(new LiteralControl("<link rel=\"stylesheet\" href=\"" + Urls.FindCSS("jquery-modalpopup.css") + "\" type=\"text/css\" />"));

I’m new to ASP.NET and to using Literals but from what I read this should be valid yet I get this exception at runtime:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I searched for similar questions of course but the use <%# solution aka databinding doesn’t work for me.

If you have any solutions or recommendations I’m listening.

Answer 1

You need to remove <% ... %> from your header and use another Literal instead.
