don't know if it helps but I've just done something similar(ish) ... I had a
class for a large jscript and simply wrote to a label.

namespace yournamespace{
using System;
public class JScript
{
private string str = "";

public JScript()
{
}
public string getjs()
{
str +="\n";
str +=" <SCRIPT language=\"javascript\">\n";
str +="<!--\n";
str +=" ......... blah blah blah\n";
str +="-->\n";
str +=" </SCRIPT>\n";
return str;
}

}
}

Label mylabel = new Label();
JScript myjs = new JScript()
mylabel.Text = myjs.getjs();
