Hi all,

I have a mobile web form with an ObjectList and a StyleSheet controls. This StyleSheet references to an external StyleSheet located in a mobile web user control.

When I use the DataBind() method of the ObjectList, I receive the following message: "The following style sheet contains a circular reference to an external style sheet:".

If I use an internal StyleSheet instead of an external StyleSheet, everything is ok.

I need to use external StyleSheet, so can anybody help me?

Hi Mr xesteban,

sorry for this delay...

i was some what busy... ok. the mistake is that you are using the Reference path in line no.4 .

ReferencePath is meant for using usercontrol stylesheet..

here you are Referening the same usercontrol as reference for itself...

there the circular reference happens ...

to avois this remove this reference path from usercontrl and use the referencepath in the aspx page only... then its ok...

Use this line instead of that one.. (Replacement for 4th line)

<mobile:StyleSheet id="StyleSheet1" runat="server">

Your code:

1    <%@ Register TagPrefix="mobile" Namespace="System.Web.UI.MobileControls" Assembly="System.Web.Mobile" %>
2    <%@ Control Language="vb" AutoEventWireup="false" Codebehind="mwucStyleSheet.ascx.vb" Inherits="Consultas.mwucStyleSheet" TargetSchema="http://schemas.microsoft.com/Mobile/WebUserControl" %>
3    <P>
4    	<mobile:StyleSheet id="StyleSheet1" runat="server" ReferencePath="mwucStyleSheet.ascx">
5    		<mobile:Style Name="Link">
6    			<DeviceSpecific>
7    				<Choice Filter="isHTML32" Xmlns="http://schemas.microsoft.com/mobile/html32template"></Choice>
8    			</DeviceSpecific>
9    		</mobile:Style>
10   		<mobile:Style Name="Textbox"></mobile:Style>
11   		<mobile:Style Name="Button"></mobile:Style>
12   		<mobile:Style ForeColor="Green" Name="Label"></mobile:Style>
13   		<mobile:Style ForeColor="Green" Name="Label2"></mobile:Style>
14   	</mobile:StyleSheet>
