    We have created a simple web user control which contains a radrotator control that uses an XML file as its datasource.  This works fine in IE but when we try to view the page in any other browse (Firefox, Chrome, Opera etc) the page just displays a blank section where the rotator should appear. 

    The user control is embedded within a page layout file using:

    <%@ Register Src="/WebControls/NewsRotator.ascx" TagName="NewsRotator" TagPrefix="CCCControls" %>

    <CCCControls:NewsRotator ID="NewsRotator1" runat="server"/>

    The code for the user control is:

    <%@ Control Language="VB" AutoEventWireup="false" CodeFile="NewsRotator.ascx.vb" Inherits="NewsRotator" %>
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
                <telerik:RadRotator width="100%" Height="180px" ItemHeight="200px" PauseOnMouseOver="false" ItemWidth="100%" FrameDuration="4000" ID="Rotator1" runat="server" ScrollDirection="Up">
                        <div class="NewsRotatorContainer">
                            <div class="NewsRotatorHeader"><h2><%# XPath("Title") %></h2></div>
                                <div class="NewsRotatorImages">
                                    <img src="<%# XPath("Image") %>" height="127" width="200" alt="" title="" style="border: 0px" />
                                <div class="NewsRotatorContent">
                                    <%# XPath("Content") %>
                                    <br /><br />
                                    <a href="<%# XPath("URL") %>" class="orderInfo">Read more&nbsp;&raquo;</a>

    With a code behind file with the following code:

    Partial Class NewsRotator
        Inherits System.Web.UI.UserControl

        Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            Dim newsSource As New XmlDataSource()
            newsSource.DataFile = "/WebControls/Rotator.xml"
            If InStr(UCase(Request.Url.ToString()), "CYMRAEG") > 0 Then
                newsSource.XPath = "NewsItems/Language[@name ='cymraeg']/NewsItem"
                newsSource.XPath = "NewsItems/Language[@name ='english']/NewsItem"
            End If
            Me.Rotator1.DataSource = newsSource
        End Sub
    End Class

    Any ideas why the control is displaying blank in any other browser other that IE??

    Hello Hefin,

    The RadRotator control, does not support values in percent and you need to use fixed values in its declaration. This restriction is by design, because the rotator control needs to know the Items' size, when it is loaded, in order to determine where an item starts or ends. In the RadRotator's declaration I suggest you specify all of the following properties: Width, ItemWidth, Height, ItemHeight (in pixels). Those properties are important and you need them in order to make the RadRotator control works properly.

    I hope this helps.
