Hello Gladys,
Unfortunately there is no lazy-loading option for the current version of RadCoverFlow. We plan to include UI virtualization in one of our next releases, but I cannot promise you an exact date. To optimize the current performance you can turn off both the loading animation and the reflection that are rendered for every item. I hope this will partially resolve your problems.
Excuse us for this inconvenience, and I hope this will not be a show stopper for you.

Thanks for the response. I think this feature will be very useful to improve the performance for coverflow. Hopefully it can be released as early as possible.
Thanks,

I know the Telerik team has done great improvements on the controls, especially when data Optimization has been an issue.
On Version 2011 Q1 , if we have 300 images can we tell the cover flow just to load just one specific one and not all of them (image) , in other words Lazy Loading the images ?,
This will increase the performance of Cover Flow tremendously !
Because if I have 50 images for example, it seems as if the coverflows needs to Know the existence of all 50 (load them all) to work moving them.. so If I click on Image #2 and then scrolls to image 50 to expand it, or show more info about it. it seems as if the coverflows needs to process all images from # 2 to # 50, why not just jump from 2 to 50 and ignore the ones in between......
If not possible with XAML how can we do it in Code ?

Hi Oscar,
You can do this in code by Add'ing and Remove'ing items from the ObservableCollection that you set as your Itemssource i.e. separate the list of choices that you present to users from the list of items associated with your CoverFlow.

RadCoverFlow now supports UI virtualization that should be of help in such scenarios.

Hello-
With support for UI virtualization, is there a limit to the number of images you could bind to the coverflow ojbect? Also I do not see UI virtualization listed in the feature set for Coverflow, I do see it in ohter controls that Grid.
I'm looking into the feasibility of using Coverflow for ~500 images.
Thanks,
-Thomas

Hi Thomas,
There should be no problem to display 500+ images in RadCoverFlow.
