Added images to CoverFlow on the fly

WebCoverFlow has prepared some client side functionality if you wish to modify the image. Here is the snippet if you wish to modify the image of item Cover1 from WebCoverFlow1 instance.

var WebCoverFlow1 = ISGetObject('WebCoverFlow1'); 
WebCoverFlow1.Items.GetNamedItem('cover1').Source = '../images/iMovie.png';
WebCoverFlow1.RefreshUIElement();

Can I also add that using javascript to add the images is perfectly acceptable if CoverFlow has client side methods to do this. I am can retrieve the URLs via AJAX no problem, I was using jQuery plugins before hand and that worked...ok, hence I am looking at this for some extra pzaz.

Hello,

I am trying to change the images in CoverFlow in an AJAX postback but CoverFlow turns white when I do. I am using primarily Telerik controls and AJAX is being managed by the RADAjaxManager. The examples I've seen of programtically adding items to CoverFlow use something called an 'ObservableCollection', which does not seem to be available to me in VB.NET (VS2008) and an unnecessary amount of effort. This is my code, which runs in an AJAX postback, what is wrong?

Dim f As New ISNet.WebUI.Silverlight.WebAqua.WebCoverFlowItem

f.Source = "http://a valid url on my server"

WebCoverFlow1.Items.Add(f)

The RADAjaxManager has been told that my update button will update the CoverFlow control but I wonder if CoverFlow and RADAjaxManager are not on speaking terms or if there is something simple I am missing.

Also, I cannot get the supplied help to work for WebAqua hence I am possibly asking a dumb and already documented question.

Regards,
