My site uses ASP.NET with themes and a MasterPage. When using the demo pages on my computer they worked fine, but when I copied the code into my site, the image in Bitmap Viewer doesn't show up. The page on which I am using the BItmapViewer has Themes disabled in the header, so I think it may be an issue with web.config, but I am stumped. How can I fix this?

I have created small sample application which uses MasterPages & Themes. It works fine with BitmapViewer, no matter whether themes are turned on or off. Could you send us sample application which reproduces the problem?

I can confirm that enabling themes in the web.config file produces the following error. No image is shown.

Hello, Stefan.

To eliminate this exception (Using themed css files requires a header control on the page. (e.g. <head runat="server" />).) you should just add head tag to your master page.

For example, here you can see my MasterPage.master :

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" > 

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <form id="form1" runat="server">
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">


<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" Theme="Theme1" EnableTheming="false" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Title="Untitled Page" %>
<%@ Register TagPrefix="aur" Namespace="Aurigma.GraphicsMill.WebControls" Assembly="Aurigma.GraphicsMill.WebControls" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
	<aur:BitmapViewer ID="BitmapViewer1" runat="server"></aur:BitmapViewer>


using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
	if (!IsPostBack)

If this does not help, could you submit case with code sample which reproduces the problem?

We confirm the issue with BitmapViewer control while using Themes. This happens when theme attribute of pages node is set in the web.config. To workaround this problem you should add to configuration/configSections node of web.config the following section:

<section name="Aurigma.GraphicsMill.AjaxControls" type="System.Configuration.NameValueSectionHandler, 
     System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

And to configuration node you should add the following values:

		<add key="RelativePublicCachePath" value="/YourProjectName/PublicCache/"/>
		<add key="RelativePrivateCachePath" value="/YourProjectName/PrivateCache/"/>

And, of course, you should create corresponding folders: PublicCache and PrivateCache.
You can read more about caching in the Image Cache Management (AJAX Controls) article.

This issue will be fixed in the next release. If the suggested solution is not acceptable for you - please submit case and we will prepare update for you.
