I'm using a web-service to pull data from a SharePoint list which is then cleaned up and bound to a Rotator. During debug I can see that the XML is clean, and when checking the rendered source I can see that there are the appropriate number of items generated. The dummy text 'Boo!' even rotates twice as expected. However, I cannot seem to bind to the underlying elements such as <%# XPath("title") %>.

Generated XML (sw)

    
            <?xml version="1.0" encoding="utf-16"?> 
        
            <newsfeed xmlns="http://schemas.microsoft.com/sharepoint/soap/"> 
        
              <article> 
        
                <title>Some Text here.</title> 
        
                <author>Smith, Steve</author> 
        
                <created>2008-02-04 16:28:43</created> 
        
                <body>Some Text here.</body> 
        
              </article> 
        
              <article> 
        
                <title>Some Text here.</title> 
        
                <author>Doe, John</author> 
        
                <created>2010-01-21 14:10:10</created> 
        
                <body>Some Text here.</body> 
        
              </article> 
        
            </newsfeed>

Code behind

    
            // code to retrieve and transform webservice feed above here 
        
            XmlDataSource1.Data = sw.ToString(); 
        
            rr_TacNews.DataBind();

ASPX

    
                <asp:XmlDataSource ID="XmlDataSource1" runat="server"></asp:XmlDataSource> 
        
                <div id="webpane">

                    </telerik:RadScriptManager> 
        
                    <telerik:RadRotator ID="rr_TacNews" runat="server" ScrollDirection="Left" FrameDuration="10000" 
        
                        Height="800px" Width="100%" ForeColor="White" DataSourceID="XmlDataSource1"> 
        
                        <ItemTemplate> 
        
                            <div style="width: 576px; padding: 12px;"> 
        
                            Boo! 
        
                                <asp:Label ID="Label1" runat="server" Text='<%# XPath("title") %>'></asp:Label><br /> 
        
                                <asp:Label ID="Label2" runat="server" Text='<%# XPath("author") %>'></asp:Label><br /> 
        
                                <asp:Label ID="Label3" runat="server" Text='<%# XPath("created") %>'></asp:Label><br /> 
        
                                <asp:Label ID="Label4" runat="server" Text='<%# XPath("body") %>'></asp:Label> 
        
                            </div> 
        
                        </ItemTemplate> 
        
                    </telerik:RadRotator>

Any ideas?

Hi Art,

You do not see the text because you set the ForeColor="White" property of the control. I suppose that you have a white background color as well and this is the reason why you do not see the text inside the RadRotator control. Could you please change the background color or set a different value to the ForeColor property of RadRotator and the problem will disappear.

In addition, I recommend you to specify the ItemWidth and ItemHeight properties of the RadRotator control. Also, I recommend you to remove the namespace that is used in the XML document or apply one of these approaches in order to able to use the XmlDataSource control:

Please do not hesitate to contact us if you have any additional questions.

The ForeColor is white because the background color of the wrapping div is dark gray. As I mentioned, when i view the generated source, I see two items as expected, but none of the subtending data items bind.

Generated Source

    
                    <div id="rr_TacNews" class="RadRotator RadRotator_Default" style="color:White;height:800px;width:100%;">

I will attempt your other suggestions.
