Question

I need to add to the page from within a custom control. I can’t use a stylesheet (.css) because I’m using a url(…) and need to resolve the url.

Right now I’m doing:

Page.Header.Controls.Add(new LiteralControl('<style type='text/css'>.xyz { color: blue; }</style>')); 

But I’m hoping for something a touch more elegant?

I guess it’s not a bad solution for the problem. If you had an external stylesheet file, this piece of code will do the work:

HtmlLink cssRef = new HtmlLink(); cssRef.Href = 'styles/main.css'; cssRef.Attributes['rel'] = 'stylesheet'; cssRef.Attributes['type'] = 'text/css'; Page.Header.Controls.Add(cssRef); 

Another idea is to write your own ASP.NET ServerControl ‘HtmlInlineStyle’, so you could call it this way (script tags would be done by your server control):

Page.Header.Controls.Add(    New HtmlInlineStyle('.xyz { width:300px;padding-left:10px }'); 

This blog entry and the comments show some alternatives (ScriptManager.RegisterClientScriptBlock). But in my opinion your solution is okay.
