c# - Injected CSS file not applied to injected markup ASP.NET 4 -


hullo everyone, building simple aspx webpage looks word in dictionary (get url query string), injects result in placeholder , formats contents appropriately retrieving css file dictionary website.

apparently can't figure out how solve third point, in fact have tried multiple approaches none seems work.

to precise, have retrieved link right css file , injected page header (tried: page_load, page_init event), query result injected in 'resultpanel' place holder in button_click event handler.

i have included aspx markup followed corresponding codebehind file project uses htmlagilitypack.

<%@ page language="c#" autoeventwireup="true" codebehind="default.aspx.cs" inherits="multidictionary.default" %>  <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server">     <title></title>     <asp:placeholder runat="server" id="hdr"></asp:placeholder> </head> <body>     <form id="form1" runat="server">     <div>         <h3>             enter url , contents of page</h3>         <asp:textbox id="textboxurl" runat="server" height="20px" width="250px" text="http://www.vandale.nl/opzoeken?pattern=kat&lang=nn">         </asp:textbox>         <asp:button id="button1" runat="server" text="get contents" onclick="button1_click" />         <br />         <asp:literal runat="server" id="resultpanel"></asp:literal>     </div>     </form> </body> </html>
