Hi there,

I am desparately trying to get the Coverflow control to work for a project I am working on.  I took the RedCoverFlowItemContainer style from the "First look" demo, and bound datacontext to a control that encompasses the CloverFlow, and set the CoverFlow ItemSource in XAML to point to a suitable Observable collection.  This yielded nothing. 

After much investigation and using the code from your Flikr data binding example I could get the items to appear.  So I gradually introduced my code (which utimately gets a list of image URLS from my business logic layer) into yours, but as soon as I used my own images the control yielded nothing.  Eventually I realized it was not the nature of my images but the quantity!

If I take your Flikr example and break out of the loop after 7 images have been added, the control shows nothing.  Conversely, If I replicate my own images so they exceeds 7 - it shows them!

I am sure I am missing something, please help, I have to get this up and running ASAP.

Thanks
Chris

I've tried to reproduce the described issue using your code but without much success. I've attached my test project, please download it and give it a try. What am I missing?

Hi Yana,
So sorry for the long delay, after the air of desparation in my original post, I go and leave it for so long to try your code!  I got around it for my demo by ensuring there were enough images .. not exactly clever ;)

So, yes your code works, but not if you encompass the coverflow in a scroll viewer for some reason, can you give that a try for me?

Thanks

Chris

Hi Krisdoff,

I've tried it with the ScrollViewer and still all the items are shown.  Can you please set Width and Height properties of the Coverflow and let us know the result?

<telerik:RadCoverFlow x:Name="coverFlow" OffsetY="100" VerticalAlignment="Center" Width="800" Height="400"  ... >

Hi Yana,

Yes, that sorted it out.  In my actual application, the size was explicitly set, but the control it was within did not have an explicit width.  It worked fine when there were more than 7 items, but less than that it displayed nothing. 

It all works now though, so thanks for you help Yana.
